Amazing performance, engine and supspension tuning come close to pure magic. Agressive styling make it best looking Bimmer out there, upgraded seats are fabulous, can fit to any torso. Exhaust sound is raspy, goofy sounding. Ride at low speed is busy, jiggly, smooths out as speed increases. A scalpel in a world of axes, makes you smile every time you drive.
Clearly one of the 6 cylinder engines on the market, more than 100 HP per liter yet docile and flexible. The supension tuning is pure BMW art, sharp turn-in, compiant, corners fast and flat. Gorgeous style with the performance just short of a race car.
Exhaust, unique to the US model, is restrictive and has a strange sound. Aftermarket "fixes" are expensive. Nervous suspension at low speeds--may be price to pay for on road razor like performanc but believe some of the jiggle could be tuned out. First to second shift, tough to be smooth, ratios.
