If you had the choice between a 56000 miles 58 Plate Z4 3.0si Sport Coupe and a 24000 miles 57 Plate Z4 3.0si Sport Coupe which would you choose. Both are a similar price, similar spec although the 57 plate has a slightly highter spec. This may be a no brainer but I am new to all this and would appreciate the thoughts of more experienced forum members. - Cheers!
