How do I buy a used car without getting burned?

Run the VIN, price the crash, decide your number before you arrive, and know the sum you will do the day it breaks. Five pages here, in that order, and a sixth that does one sum before all of them: the cost of a whole year of owning the car.

Take the VIN to the dealer first. Take the VIN to the dealer before the cash changes hands began under a photo of someone’s payment-free 2001 wagon, when a person who had owned two of the exact same car listed what the years taught them. Item one: make sure the recalls were actually fixed. Recall repairs are free and owed to whoever owns the car now, but nothing forces previous owners to have claimed them, so a used car can carry an open recall like an unexploded coupon. Any dealer of that make can run the VIN, and in the US you can do it yourself at NHTSA.gov/recalls. One honest edge: in the US the free-repair obligation runs out fifteen years after the car was first sold, so on a twenty-year-old car the lookup tells you what is unfixed and the repair itself may no longer be free.

Price the crash too. When you shop for a car, price the crash too is the question someone asked under posts like the proud one about a 1999 sedan for three thousand dollars: what happens to the person inside it when something goes wrong? The person who settles it lived the downside, a crash that cost a month-plus hospital stay and a year of follow-up visits and rehab, and took two things from it. The bargain maths is a lie, because the money a cheap unsafe car saves is a rounding error against a hospital bill. And you cannot opt out by being careful, because you do not control anyone else on the road. The counsel is sized for a real budget: not spend more, spend the same, one decade newer, the unremarkable car over the charming one.

You can leave the dealership mid-sentence. You can leave the dealership mid-sentence says your advantage is that you are allowed to leave at any moment, and the tactics on the lot depend on you staying in the chair. Decide your highest out-the-door total including taxes and fees before you go, get pre-approved at your own bank or credit union, keep the trade-in out of the conversation until the price is settled, and bring a spare key for it. Some people negotiate by email first, asking a handful of dealerships for written out-the-door quotes on the same car. In the room, read every line, because interest rates and add-on warranties have appeared on final documents after everything was shaken on. The brightest line: your property is not a negotiating chip, and a lot that holds your keys to hold you is a lot you leave loudly. Everything there describes US dealer culture and law.

Give one garage the small jobs first. Give one garage the small jobs first is for after you own it. Some people say the defence against a padded bill is not knowing more than the mechanic but finding one who wants a long-term customer; some people say the way in is the small jobs, the oil, the yearly check, done at the same place until you are a face and not a stranger. Four checks need no car knowledge: ask to see the old part, get a second opinion on any big quote, check the work afterwards, and look up what the labour should take. The page keeps how the relationship fails: loyalty to a bad garage is just paying a bad price for longer, so pick by word of mouth first and stay only once it has earned it.

Know the sum for the day it breaks. If the repair costs what the car is worth, it is not a repair is people doing the same arithmetic: write the repair cost next to what the car would sell for today, and if they are close, the repair is a second purchase of a car you already own. Check the diagnosis first, because theirs were wrong; one dead engine was a belt. Its safety lines, from the people and from US guidance: do not put down a deposit as big as the car, do not co-sign someone else’s refinance, there is no general right to return a car once you have signed, and handing the car back does not hand back the debt.

Before you decide on a car, add up a year of owning it, and buy it only if the total fits your budget. Price a year of running the car before you buy it says the number on the window and the number on the loan quote are the two bills you can see before you sign, and that insurance, fuel, registration and the repair nobody scheduled come later, with no one at the desk to explain them. On one sheet, write a loan payment from a real loan quote, an insurance quote for that exact car, what fuel costs you in a year, registration and taxes, and an amount set aside for repairs. Add them and compare the total with what you can pay every month with something left over. If it does not fit, the car is the wrong one, not your arithmetic. The US Consumer Financial Protection Bureau makes the same point: it is tempting to work out a monthly payment from the price alone, but that leaves out the interest rate and APR, taxes and fees, optional add-ons, auto insurance and ongoing maintenance. Many people say the real cost of a car is upkeep and repairs, and that it can be far higher for a luxury car or an older one, and some say the other running costs can cancel the saving from a cheaper payment.

Two traps from that page. One is a used luxury car priced about like a new ordinary one: it looks affordable, but you still own a high-value car whose parts are priced to match. One person says repairs on luxury cars can run far above what the same repair costs on an ordinary one, and some people put it as a rule of thumb that if you could not afford two of that car, you cannot afford one. There is dissent: one person says they owned three cheap used luxury cars that cost almost nothing to maintain, and none of it tells you what yours will cost, so ask for a repair-cost estimate for the specific model before you buy. The other is the loan length. The bureau says a shorter term costs less overall and a longer one lowers the monthly payment but means you pay more interest; its own example is a $20,000 loan at 4.75 percent, which comes to $597 a month and $1,498 in interest over three years, and $320 a month and $3,024 in interest over six years. Your rate will differ. If you owe more on your current car than it is worth, a dealer or lender may offer to roll the balance into the new loan, but the bureau says that makes the new loan more expensive; if a dealer promises to pay off your old balance, check that it is not folded into the new loan or the final contract. The bureau says to refuse a form with blanks left in it, and that the loan disclosure states whether you can prepay without a penalty.

New against used is argued on the page, not settled: some people say a new car loses value so fast that you can owe more than it is worth, others that if you plan to keep it for ten or fifteen years the early drop stops mattering and buying new means you control the maintenance from the start. Run the sum for both cars. If you need a car and have little choice, for work or for care of someone, the yearly total is a way to choose among the cars you can afford, not to talk you out of one. The page is not for someone who already signed: if you are holding a loan that is underwater, your lender and a nonprofit credit counselor are the place to start, and the page does not cover how to get out of it. It is about buying a car in the United States, and car finance in the UK and elsewhere works differently. Whether to spend on a car you love is a values question the page leaves open; the sum only tells you which one you can afford.

Who this is not for. If you are buying at a posted-price, no-haggle dealer, the game the walk-away defuses is not running. If the car is leased, one person there says the lease removes the garage question; under warranty, the dealer strand of that page is yours. And outside the United States, the pressure may rhyme but the rules and remedies on these pages will not.
