Look at it this way no matter how your car were to perform against his "belly button" 135i it would make up in, Class, individuality and most of all taste.
Polish them up, park them in a lot, and watch which one people come up to and stare. No one loves the looks of my SRT more than I but I have to tell you it really feels fantastic to watch people stare. Just be prepaired to talk about it a lot, there will be questions.
Buy it while you have the chance!
