Hi Graham
You have posted this in the UK M3 section, you would get a better response in the E90post section
The E9post forum is mainly 'designed' for owners of E90 (saloon), E91 (tourer), E92 (coupe) & E93 ('vert) models of the laterst shape BMW 3 series (55 plate onwards) - Your budget sounds too low and I guess you are looking at older E46 shape BMW's - maybe E46fanatics.com may be more suitable if so?
Cheers, Paul
