Flip a used car

Know the law first

Most states cap how many vehicles a person can sell in a year without a dealer license, commonly three to five; selling more, or selling cars you never titled in your name, is "curbstoning" and carries fines. Utah and its neighbors differ; look up your state's DMV page before your second car. Title every car you buy in your name, pay the tax, and sell it as the owner. That one habit keeps you legal and makes buyers trust you.

Before you drive

• Ask for the VIN and a photo of the title. No title, or a title not in the seller's name, or a "title coming" — no deal, no exceptions.
• Run the VIN: an NMVTIS report (a few dollars through any approved provider) for salvage / flood / odometer brands, and a paid Carfax or AutoCheck if the car is over $5,000. Accident history is fine at the right price; a salvage or rebuilt title is a different market entirely.
• Ask about a lien. If a bank holds the title, the payoff has to happen at the bank with you present, or the seller has to clear it first.
• Ask why they are selling and how long they have owned it. Short ownership and a vague answer is a flipper dumping a problem.

In person

• Cold start. Arrive early so the engine is cold; a car that "was just warmed up for you" is hiding a start-up noise, smoke or a misfire.
• Fluids: oil color and level, coolant color (milky = head gasket), transmission fluid smell (burnt = walk).
• Under the car with a flashlight: rust on the frame rails and subframe, fresh undercoating (hiding rust), leaks.
• Tyres: uneven wear means alignment or suspension; four different brands means a car nobody spent money on.
• Every electrical thing: windows, locks, AC on full cold, heat, lights, wipers, dash warning lights on start-up and that they go out.
• Test drive: highway speed, hard brake, tight turns both ways, a bumpy road. Listen with the radio off.
• Pre-purchase inspection at an independent mechanic ($100–200) for anything over $5,000. If the seller will not allow it, that is the inspection result.

Paperwork

• Title signed by the seller exactly as their name appears, odometer disclosure filled in, no corrections or white-out (an altered title is void in most states).
• A bill of sale with VIN, price, date, both names and addresses, "sold as-is" — two copies, both signed.
• Photo of the seller's ID next to the title. Cash, counted at the bank if it is over a few thousand; or meet at the bank and let the teller count it.
• Insurance on the car before you drive it away; a temporary permit if the plates stay with the seller.

Reconditioning that pays

A $150 professional detail returns $500 on a car under $10k; nothing else comes close. Then: tires if below the wear bars, brakes if they pulse, a windshield chip, a dead bulb, the check-engine light diagnosed and fixed (buyers read the code themselves now). Do not paint, do not do cosmetic bodywork, do not "fix" a transmission. The margin is in cars that need cleaning, not cars that need repair.

Selling

Photograph it clean, in the shade, twenty photos including the odometer, the tires, under the hood, every seat and any flaw. List with the year, trim, mileage, title status ("clean title in hand") and what you did to it. Price at the market number and expect to take $300–500 less. Meet buyers at the DMV or a bank; never let someone test-drive alone; keep their license in your hand while they drive with you in the car. Sign the title only when the cash is in your hand, and file the release-of-liability with the state the same day.
