personally i'd look at one with rust but then i'm a panel beater. if on the other hand i was a mechanic i'd look for one without rust.
go for whatever your ok with fixing yourself..i've had my saph for 5 year's now. it was'nt mint when a got it but it was'nt far from it.. now with being up in the shetland's for 5 year's it need's the body sorting. engine is still at 160K withuot a rebuild.. to my knowlege that is..
