I sold my zed 3 years ago for 7k, would probably still sell for around that today
My r33 gtst I bought for £3300, a couple of years later it got written off and I was paid out £5500
Iv noticed loads more. Was considering an s14 a while back. Used to be plenty for under 2k, now they're nearer 4
S13s- used to be a good few for under 1500, now you can't find many for under 2
I think a lot get tracked/written off/broken for parts so fewer in the road also help prices rise
