There's not much room under the bonnet I don't think lol. Neither of my zeds of had history, think this one has a few part receipts but that's it & its fine,so far at least.
I had a white one previously, not many about really, especially factory white ones. I looked at a white one with an n1 kit before buying this, that was resprayed from blue, wasn't very tidy either.
£7000 should give you a good choice mate
