If I list all the faults, would you give me a realistic price, as i like the car them selves,maybe buying a good one would be the most cost effective for me
I think you are probably right to trade-up. Just make sure it's a good one this time! Ask someone from the forum to go with you perhaps.
Personally I wouldn't list all the faults here as a potential buyer may find it. There's being truthful and there's shooting yourself in the foot.
You're welcome to PM me for help. But it would have to have been accident damaged for it to be worth any less than £1,500. I'd be tempted to put it on ebay as an open auction with a start price of £1,350 and see where it goes. I'd be surprised if you didn't get close to your £2k back. Or a fixed price at £2,200 and ask for offers if you prefer. I can't really give any more specific guidance than that though. There's no exact price for any car. So I'm saying get the best money you can between £1,350 on a bad day and £2,200 on a good day.
Perhaps the more important thing to concentrate on is the wording and photos in the ad. Again happy to help there if you want to draft something up and send it to me.
And please, anyone else weigh in with advice. I spend silly amounts of time studying cars for sale but a range of opinions is always good.
