Faults:

No problems so far, but it does take the A/C a few minutes to cool the cabin down in 100 degree weather, and the engine burns a little oil, but there are no oil leaks.

General Comments:

This is a seriously quick car. The seats feel like they wrap around your body, and the handling is like being in a sports car.

This car is so much fun to drive; the 550 has the M-Sport package, so it has a very muscular body.
