1600kms here, i will list them from Most Important to Less Important:
1. A "clunk" noise from boot lid from time to time
2. Some minor "rattles" from front suspension when going 15-20mph over uneven/broke pavement (i think 21"s has something to so) like i have no bushes. For example if i drive my E70 with 20"s RFTs the same road same speed i goes very smooth
3. Drivers seat wear very quickly
4. A small rattle from center console (haven't identified it yet)
5. LBB colour is like a magnet for bugs!
