What it is

A small used car business run from home or a rented space. You buy cars at auction, from trade contacts or from private sellers, tidy them up, then advertise and sell them through online listings and social media.

Your first three steps

  1. Register as a sole trader or limited company and tell your motor insurer you will be trading, as a trade policy is usually needed
  2. Set aside money for two or three cars and learn how to run vehicle history checks and spot problems
  3. Buy your first car, photograph it well, list it online and write down every cost so you know your true profit
Who pays

Private buyers looking for an affordable used car, often first-time buyers, families and people replacing a car quickly.

How it makes money

You sell each car for more than you paid, after covering prep costs, any repairs, advertising and warranty. Profit per car varies a lot, so careful buying matters most.

Skills that help
  • Judging a car's condition and value
  • Negotiating with sellers and buyers
  • Basic bookkeeping and record keeping
  • Honest, clear customer communication
Watch out for
  • Motor trade insurance, as standard car insurance usually does not cover buying and selling cars, so check cover with a specialist broker
  • Consumer rights law: cars sold by a trader must generally be of satisfactory quality and as described, so check what applies to you
  • Buying cars with hidden finance, clocked mileage or write-off history, so always run a history check
  • Whether you can trade from your home address, which may depend on your landlord, mortgage lender or local council
  • Consumer credit authorisation, which you may need if you arrange finance for buyers, so check with the Financial Conduct Authority
  • Tight cash flow, as money is tied up in stock until each car sells
