Hey buddy,

I'm in the final process of trading in my 09 Z touring w/ sport package for a 2012 bmw 135i. Since you have owned both, I was hoping you would give me your opinion regarding power and overall driving fun. My Z just doesn't have enough power for me anymore. The car is lightly modded: Gen 2 stillen intake, test pipes, exhaust, Uprev tune. I love the Z, and it's a great car, but I want a lot more power and the Z just doesn't have the potential dollar for dollar. Let's say compare a Z with the bolt ons listed above vs. a stock 135 w/ only a JB4. Please advise when you have a moment, and thank you for your time to read and respond.
