Estimates for a small start in the UK, not guarantees.

What it is

You buy used parts such as mirrors, alloys, lights, seats and electrical items from salvage auctions, dismantlers and trade contacts. You test and photograph them, list them on marketplaces or your own site, and post them out from home.

Your first three steps

  1. Pick a niche, such as one make or a type of part, and check recent sold prices on marketplaces
  2. Buy a first small batch from a dismantler or trade auction and set up a space at home to store and test it
  3. Open a seller account, list your parts with part numbers and compatibility details, and price postage carefully
Who pays

Drivers doing their own repairs, independent garages and bodyshops looking for cheaper parts than new.

How it makes money

You sell each part for more than you paid, plus delivery. Profit comes from choosing parts that sell reliably, listing them accurately and keeping returns low.
