well, i haven't ordered the car yet, but i plan to go for a 325xi e91 with 160 rims.
the all-wheel-drive 325 version has the bigger brakes of the 330, thus, awd drivers cant use 16" rims.
i would go for 16" instead of the 17" - just because of the comfort (noises).
anyway, let me know how the 17" behave in greece...
thx and enjoy!
PS: i am very sensitive regarding noises. i drive a saab convertible, and every little pothole has the impact of an earthquake...
