A chap over on .org and XPF is selling his trophy yellow 180 saloon. I've known him for for a few years so can vouch for him and his car.
Linky
here to thread on .org. Don't worry, you can read the thread without having to register
It's a 51 model, not long had it's 90k service with all belts done by Lates, Piper cat-back and ITG, approx 64k miles and all for £2500. I would say that is a good price for such a car and worth considering.
He's based in Southampton btw.
