I know I said I wouldn't post crashes but this is funny because it is two nearly new BMWs and nobody seems hurt.
Stabilty control failure or just crap brakes - all road testers say the M3 brakes are a bit feeble for the car's performance so a mundane 330 must struggle to stop. This one did until it got on its roof.
It was not the fault of the blonde Z4 driver. Her car looked pretty well intact.
