I was at my friends BMW collection yesterday, which included a completely MINT e30 M3.
We took it out for a couple hours, and I have a whole new respect for it.
Collection included (but not limited to)
M3 (E30, E46 Cab, E92)
M5 (E39, E60)
I'll try to grab some pics off my phone this weekend.
Forgot to mention the best part...
He tracks every one of them. M1 included!
