I'd be very very interested in your take on how your 135i handles, especially concerning throttle control while cornering.
I'm considering a 128 or 135. While I like the idea of more power on the 135, I'm concerned about throttle feel while cornering. For example I've been playing around with my wife's 335i cornering and I'm finding I'm having trouble modulating the throttle smoothly with the turbo. On naturally aspirated engines it's been so much easier for me feeling the throttle.
