Mine was,
I bought a Renault 21 turbo for £250 on a k reg( last made) absolutely mint other than, damaged front passenger door, front bumper in the boot.
The bloke was quoted £2k to repair it so just wanted rid of it.
I got a new bumper bracket for £5, and refitted it. And bought a mint passenger door in the same colour for £25.
So for £280 I had a mint car.
Then the gearbox failed but I had a spare so fitted that, it owed me £150, so £430 in total.
I then sold it for £1000 and a Renault 5 gt turbo with loads of mods.
I then hook about £1500 worth of mods off the 5, Inc. Big front brake kit, big exhaust system, silicone hose kit, new diesel rad, external oil cooler kit, front mount intercooler kit.
Think that's it. Put all the bits on my convertible 5, then mopped the other 1 and sold it for £1500.
That was the 1 and only time it's happened to me tho lol
