Yeah I just think I want to experience a newer M3 before they go down the blown route.
It isn't an easy decision though, the 135 is equally as quick as the M3 (a good friend of mine owns an E92 M3) and the running costs are halved.
All the things that make it Not and M car are also the things that make it so lovely to drive on a daily basis.
The two main things I miss are a proper slippy diff and the noise. Its not all positives though, the brakes are arguably better on the 135, with more staminar from the 6 pots.
You are right with your closing statement though, its not an M car. ;-)
