I've had about 73 cars now and I'm really really fussy with them.
I've bought lots of 1 owner cars, and it also really annoys me when I go to see a car where the owner has decided to throw away all receipts/MOT's etc from new because they didn't think they needed to keep them and that the stamps in the book were enough! WTF?!
I keep everything, literally everything with a time, date and mileage listed on all part changes.
My Integra DC2 which I bought from the first owner has everything from new, I mean everything including the original purchase invoice. My Mercedes is also the same! And, to be honest, my Clio 182 isn't far off!!
