BMW has kicked off its new line of M Performance accessories and is promising a full line for all of its models. Add this to the four different interior styles on the new 3-series and we're looking at millions of configurations so that the moderately wealthy can feel more like their new, expensive car is a personal expression. This isn't just BMW though, Abarth has announced a customization programe for the Fiat 500 Abarth and Volvo was showing off a variety of new R-Design trims as well. Oh, and the new SRT Viper is said to have up to 150,000 options. Seeing as dealerships make most of their money in accessories these days, expect this to continue.
