What kind of mods would you guys recommend for a 2007 BMW Z4 3.0i (roadster)?
I’m thinking of buying a Z4 E85 2.5 or 3.0 (M54 but if I’m lucky N52).
What are the weaknesses? On what do I have to look at? Do they have rust problems? Does the soft top start leaking with age?
I’m thankful for every tip!
