I've sat in the new SRT300 and I have to admit that it has a very luxurious interior and the driving feel isn't that bad either. But with my experience with American cars, it won't last long. The interior will probably fully degrade within a year and be riddled with rattles/random noises and the car will probably be in the shop every other week.
M3 is gone. Pretending to be a dad now with an X5...
