I'm thinking of getting a used F10 M5 in the next few weeks and after some buying tips and advice.

Budget is circa 35-40k and after as high a spec as i can get. Ideal colour combo is Monte Carlo blue with Sakhir orange interior, and ideally the comp pack.

Luckily it seems quite a popular combo and there are plenty about, been looking on pistonheads mainly.

Is there any specific things to look out for or avoid? Thanks
