First time I've seen one. There was a time when I was a bit intrigued by this car, but meh..
Ya know, if you can stop yourself at a set of AutoX Tires, you will just need to do slightly more maintenance and replace brake pads sooner. If you have a car thats built well (which, BMW's are) and you drive it pretty smoothly, I dont think you are putting that much wear and tear to increase your costs much. Yea, it can get ridiculously expensive but Ive sacrificed some of my photo budget to it because its just way - too - fun.
This is my problem, I don't do moderation
Though at this point I'd just be happy to get my car back. Haven't had it since the end of May
