I have a similar problem moving trade stuff on. sub £1k cars
Any ideas where we can get rid - i have a trial with cartotrade however they want £40 a month!
At the minute I advertise them as trade cars on AT/Website/Gumtree & Ebay I give no warranty ( which is legal ) and any issues found on safety check ( which we do to every car ) are listed, the car is priced according to its faults / condition and that's that. However we ensure its roadworthy, so brakes/tryres/MOT failure Items are sorted.
Our cars are fit for purpose ( they start, stop, run and drive )
Satisfactory quality ( based on asking price )
As described ( if anything i'm too honest and show people every nick, scratch, broken trim etc )
I had a Punto 4 weeks ago - 2 days in, gearbox smashed to bits in 5/6th, it worked when I drove it, when he drove it on test drive and for the previous owner had it for 6 years - However being a realist, I didn't want to see a young lad with a £1000 gearbox bill, I found a box, had it fitted and he contributed £150 to the bill. We spoke about it like grown ups and hes driving his car now with a smile on his face. I lost £200 overall on the deal but it was a px for a deal that I made £800 on, so i'm still up.
I think with these things, if it breaks, fix it or give them their money back.
I use Lawgistics for their self underwritten warranty product ( which works for me ) and they are always very helpful by the way.
Mat ( sorry about all the brackets, i have no idea why I do that! )
