Turbo Lag!!!
 I love the styling and the car proved to be a joy to drive... until I got my software updated. Instead of boost coming on before 2k RPM as advertised, there is now a significant amount of turbo lag. BMW has altered the performance of my car without my permission, possibly to minimize wear and warranty issues with the turbos. Until this problem is resolved, I would NOT recommend a 335.
