hi,looking at a 04 new shape 5 series 2.2petrol... its really cheap (4-7k less than others) but has 125k miles on the clock....as i only wanted a sunday car i thought it might be ok? also it has bmw fsh and a 12 month warranty...i also know the only previous owner and its nearly all motorway miles....would really appreciate any advice you could offer! cheers!
