Buying a used car: the complete guide
Buying a used car well comes down to four things in order: deciding what the vehicle has to do, verifying its condition and history, understanding what you are paying in total, and confirming the paperwork. These guides cover each step.

Buying a used car
Most used-car mistakes are not made at the point of purchase. They are made earlier, when a buyer skips the step of defining what the vehicle actually needs to do, or later, when a cost that was never discussed shows up in the first year of ownership.
The guides below follow the sequence a careful buyer works through, from choosing a body style to inspecting a specific car to knowing what a vehicle history report can and cannot tell you.

How to buy a used car, step by step
How do you buy a used car?
Buying a used car works best in a fixed order: set a total budget including running costs, define what the vehicle must do, build a shortlist of two or three candidates, inspect and drive each one, verify history and title, agree the total price rather than the payment, then complete registration and insurance.

Used car inspection checklist
What should you check when inspecting a used car?
Check five areas in a fixed order: body and structure for rust, filler, and uneven panel gaps; tires and brakes for wear patterns; the engine bay on a cold start for leaks and fluid condition; every interior switch individually; and underneath for corroded brake lines, fuel lines, and subframes.

Vehicle history reports, explained
What does a vehicle history report tell you?
A vehicle history report shows what was reported to its data sources: title brands such as salvage or flood, odometer readings captured at registration and inspection, police-reported accidents, insurance total-loss claims, the states the car was registered in, and service entries from shops that report. Unreported damage leaves no record.

The used car test drive checklist
What should you look for on a used car test drive?
Drive a route you choose that includes rough pavement, a highway on-ramp at full throttle, a steady cruise near 60 mph, a firm stop from 45 mph, and full-lock turns in a parking lot. Keep the radio off and listen for clunks, driveline vibration, harsh shifts, and brake pulsation.

Dealership or private seller: which is right for you
Should you buy a used car from a dealership or a private seller?
A dealership handles title transfer, registration, and sales tax, is licensed by New York State, and can service the vehicle afterward. A private seller usually asks less and sells as-is, leaving the DMV paperwork, the tax payment, and the full risk with the buyer. The difference is work and recourse, not only price.

Mileage or age: which matters more on a used car
Does mileage or age matter more on a used car?
Neither number decides it alone, because they wear different things. Mileage consumes moving parts such as bearings, clutch packs, and suspension joints. Calendar years degrade rubber, hoses, seals, fluids, and, on salted coastal roads, steel. Maintenance history outweighs both, so read the two numbers together and price the gap.

Choosing a body style: SUV, sedan, truck, or minivan
Should you buy an SUV, a sedan, a truck, or a minivan?
Choose for your ordinary week, not your busiest weekend. A sedan costs the least to run and parks anywhere. A crossover trades fuel economy and tire cost for ride height and cargo access. A minivan moves people and gear better than either. A pickup earns its place only if you tow or haul regularly.

Used car red flags worth walking away from
What are the warning signs of a bad used car?
The clearest warning signs are a title that does not name the seller, a check engine lamp or recently cleared fault codes, mismatched paint and uneven panel gaps, fresh undercoating over rusted areas, silt or corrosion suggesting flood exposure, and any seller who resists an independent pre-purchase inspection.

Questions to ask before buying a used car
What questions should you ask before buying a used car?
Ask why the vehicle is being sold, who maintained it and whether receipts exist, whether it has been in a collision, whether the title is clean and in the seller’s name, what work it needs now, when the inspection sticker expires, and whether you may take it to your own mechanic.
