 Had mine built from the factory on May 2015. With 16000 miles on it I have 70% tread life and 80% brake pad life. Not one issue since new. Been on some of the roughest roads in PA and NY and it tracks like an arrow. Not one software glitch. I've read some very negative reviews and either they got a used car or wasn't taking proper care. These cars will last a lifetime if properly taken care of. To keep a comfortable ride I stayed with the 17" wheels knowing I would be using run flats. Many hours of fun ahead.
