Vehicles and Automotive

Act as a car detailing expert who teaches beginners. I want to take care of my car at home. Car: model, year and color. Paint condition: new, light scratches, dull, stained. Where I wash it: covered garage, street, apartment complex with no hose. Products and tools I already have: list. Budget for what is missing: amount. Time available: hours. Follow these steps: 1) Build the supply list in two columns, essential and optional, with what each item does and a cheaper alternative. 2) Describe the wash step by step in the right order, from wheels to roof, explaining the two-bucket method and the mistakes that cause scratches and swirl marks. 3) Explain drying and paint decontamination, and when it is needed. 4) Compare wax, sealant and ceramic coating in a table: durability, difficulty, cost and which case each one fits. 5) Include the interior: dashboard, cloth or leather seats, glass and floor mats. 6) Create a maintenance calendar: what to do weekly, monthly and every six months. 7) Adapt everything if I have no access to a hose, using a rinseless or waterless wash. Rules: warn me which household products damage paint, such as dish soap. Tell me which defects cannot be fixed at home and need a professional. Do not recommend brands, describe the type of product. End with a one-page checklist I can follow on wash day.

Act as an experienced auto mechanic who explains things clearly to people who know nothing about cars. My car is making a strange noise and I want to understand the likely cause before I take it to a shop. Car details: - Make, model, year and mileage: make_model_year_mileage - What the noise sounds like (squeal, click, grinding, hum, clunk, whistle): noise_type - Where it seems to come from (front, rear, a wheel, engine, underneath): location - When it happens (braking, turning the wheel, going over bumps, accelerating, at highway speed, cold engine): when - How long it has been going on and whether it is getting worse: duration - Other signs (vibration, smell, dashboard light, car pulling to one side): other_signs Follow these steps: 1) List 3 to 5 likely causes, from most to least likely, explaining in plain language why each one matches my description. 2) For each cause, give an urgency level: can wait until the next service, get it checked this week, or stop driving now. 3) Suggest simple, safe checks I can do myself to tell the causes apart (for example, listening with the windows down or repeating the situation on an empty street). 4) Name the parts usually involved and a rough range for parts and labor, noting that prices vary by region and shop. 5) Write a 3-sentence description of the problem I can give the mechanic, to avoid a wrong diagnosis and unnecessary part swaps. End with the warning signs that mean a safety risk (brakes, steering, suspension) and when to call a tow truck instead of driving. Make clear this is guidance and does not replace an in-person inspection.

Act as a tire specialist who explains everything to people who know nothing about cars. My details: - Car: make, model, year - Size printed on the current tire: e.g., 205/55 R16 91V - Manufacturing date (DOT code, last 4 digits): e.g., 2321 - Driving: city, highway, gravel, about miles/km per month - Tire condition: visible tread, wear on one edge, bulges, cracks, steering wheel vibration - Climate: hot, rainy, snowy winters - Budget for a full set: amount - Priority: longevity, comfort and low noise, wet grip, lowest price Follow these steps: 1) Decode every part of my tire size and DOT code, including the tire's real age. 2) Tell me whether it's time to replace them, based on the tread wear indicators, age and the signs I described. If any sign is an immediate safety risk, say so first. 3) Explain what uneven wear points to (alignment, pressure, suspension) and what to ask the shop to check. 4) Show how to read load index, speed rating and any tire label or rating, and the minimum values my car needs. 5) Compare 3 tiers (budget, mid-range, premium) and, if relevant, all-season vs. winter tires, in a table with pros, cons and who each suits. Don't make up prices: tell me how to research them. 6) Give a checklist for buying and installation (balancing, alignment, rotation, initial pressure) and a monthly care routine. Always remind me to confirm the correct size in the owner's manual or door-jamb sticker before buying.

Act as an experienced mechanic who explains things simply to people who don't know cars. A warning light came on in my dashboard and I want to know what it means and what to do right now. Details: - Car: make, model, year and engine - Mileage: miles or km - Light that came on: describe color, symbol shape and whether it's steady or flashing - When it came on: e.g., at startup, on the highway, after hitting a pothole - Other symptoms: e.g., noise, smell, loss of power, smoke, high temperature, none - Where I am: e.g., in town, on the highway far from a shop Follow these steps: 1) Identify the possible lights matching the description and explain the difference between red, amber/yellow and informational warnings. 2) Rate the urgency: pull over safely now, drive carefully to a shop, or schedule a service. 3) List simple, safe checks I can do myself (e.g., oil and coolant levels with the engine cold, gas cap, tire pressure), explaining how to do each. 4) Tell me what I should absolutely not do in this situation. 5) Point out the most likely causes, from simplest to most serious, with a repair cost range clearly marked as a rough estimate. 6) Write a short summary of the problem to show the mechanic so I don't pay for unnecessary work. Remind me that the owner's manual is the reference for the exact symbol and that a final diagnosis requires a professional.

Act as a traffic and insurance advisor who helps drivers stay calm and act correctly right after a minor collision. Situation: - Location: city and country - Type of accident: rear-end, side impact, parking lot, parked car hit - Injuries: yes or no - Other party: driver present, drove away, parked car with no owner around - My insurance: insured with or without liability coverage, or uninsured - Other driver's insurance: yes, no or unknown - Visible damage: describe Guide me in this order: 1) The first 10 minutes. Scene safety, hazard lights and warning triangle, when to call emergency services or the police, and when it is okay to move the cars out of traffic. 2) What to document. A photo list (angles, license plates, car positions, road signs), details to exchange with the other driver and witness contacts. 3) What to avoid saying or signing at the scene. 4) Whether I need to file a police report or an equivalent record where I live, and how to find the deadline and the official channel. 5) How to file an insurance claim, what to report, common documents and questions to ask about the deductible, rental car and repair shop. 6) If nobody is insured, how to get repair quotes and put a settlement with the other driver in writing. Also write a short, polite message to send the other driver confirming the details we exchanged. Do not present legal deadlines or fault rules as certain. Tell me where to confirm each one (insurer, local traffic authority or a lawyer). If anyone is hurt, the first instruction is to call local emergency services.

Act as an automotive consultant specialized in total cost of vehicle ownership. I will give you my car data and I want to know what it truly costs me per month and per mile driven. My data: - Car: model, year and engine - Monthly mileage: miles or km per month - Fuel economy: city mpg or km/l in the city and highway mpg or km/l on the highway - Fuel price today: price per gallon or liter - Fixed annual costs: registration/tax amount, insurance amount - Maintenance over the last 12 months: amount spent Follow these steps: 1) Calculate the monthly fuel cost, separating city and highway driving. 2) Add fixed costs, maintenance and estimated depreciation, then present the total cost per month and per mile. 3) Build a table with the rows Fuel, Maintenance, Insurance and taxes, Depreciation and Total. 4) Compare my cost per mile with a typical figure for this class of vehicle and tell me whether I am above or below it. 5) Point out the three expenses with the most room to shrink, and exactly what to do about each one. Show every calculation explicitly and flag any number that is your estimate rather than data I provided.

Act as a riding instructor and motorcycle buying advisor. I want to buy my first motorcycle and I need a realistic recommendation based on how I will actually ride, not on brand loyalty.

Show the costs in a table and treat safety as a criterion that outranks performance.

Act as an independent car buying advisor with no brand affiliation. I want to decide which type of car actually fits my real usage, comparing electric, hybrid and gas. My situation: - Average monthly mileage: miles or km per month - Typical driving: city, highway or mixed - Where I park at home: garage with an outlet, garage without one, street - Charging access along my routes: yes, no, not sure - Fuel and electricity prices in my area: values - Purchase budget: amount - How long I plan to keep the car: years Follow these steps: 1. Calculate the cost per mile or km for each option using my numbers and show the math. 2. Estimate total cost of ownership over that period, including purchase, energy or fuel, maintenance, insurance and expected depreciation. 3. List the practical friction points of each option in my case, such as charging time, real world range and service availability. 4. Point out the scenario in which each option stops making sense. 5. Recommend one option and name the single variable that would flip that recommendation. Show steps 1 and 2 as a comparison table. Make clear which figures are estimates and which depend on data I still need to confirm. Do not invent prices for specific models, use ranges and say when a number is approximate.

Act as an experienced mechanic who explains things in plain language. My car is a make, model and year with mileage on the odometer. I drive about distance per month, mostly city, highway or mixed. My recent service history is what was done and when. Follow these steps: 1) Build a preventive maintenance calendar for the next 24 months, organized by mileage and by time, whichever comes first. 2) For each item, explain what the part does, the risk of delaying it and an estimated cost range. 3) Separate what is mandatory, what is recommended and what can wait. 4) List 5 warning signs (noise, smell, vibration) that mean something is wrong before the next service. 5) Present everything as a table with the columns Item, When, Priority and Estimated cost. Rules: use the manufacturer manual as your main reference, warn me when the recommendation changes by trim level, and never suggest a repair that needs specialized tools without pointing me to a shop.

Act as a driving instructor with 15 years of experience preparing students for the written theory test. I take the test in date or number of weeks and I have example, 40 minutes a day to study. My starting point: never studied, already failed once, just reviewing. My weak areas: road signs, first aid, basic vehicle maintenance, defensive driving, or "not sure". Build for me: 1) A day-by-day study plan up to test day, weighting each module by how heavily it appears on the exam (traffic law, defensive driving, first aid, environment and shared road use, basic vehicle maintenance). 2) A tight bullet-point summary of each module covering only what actually shows up. 3) The 20 most common trick questions, explaining why the wrong answer looks right. 4) A 30-question practice test in the official format, with the answer key and explanations only at the end. 5) A table of violations and penalties organized by severity for me to memorize.

Use current traffic law for my region and flag any rule that changed recently, reminding me to confirm it on the official licensing authority website.

Act as an experienced mechanic working on the customer's side. My car is a model, year, engine with mileage on it. The symptom that took it to the shop was describe. Here is the quote I received: paste the line items, parts, labor hours and prices. Analyze it this way. 1) Sort the items into three groups, meaning needed now for safety, recommended soon, and can wait or unrelated to the symptom I reported. 2) For each item, explain in plain language what the part does and why it typically fails on a car with this mileage. 3) Flag labor that is normally already included in another line item, so I am not billed twice, and parts that shops often add without real need. 4) Estimate a reasonable price range for parts and labor, making clear it is an estimate and that prices vary by region and shop. 5) List ten direct questions to ask before I approve the work, covering warranty on the repair, part type (OEM, aftermarket, remanufactured) and getting the old parts back. Finish with a short script for asking for a second opinion without creating friction with the shop.
