Looks aside - 135i > 235i

[gap]

I'll skip the ascetics of 235 vs 135 since it is so subjective.
I've had my 135i 6MT since 08 and test drove a M235 last weekend.
As many have said stock for stock the M235 suspension is way better than
stock 135i. After adding PS, rear subframe inserts, M3 control arms and Michelin PSS my 135 feels better than the M235. I've done a few power mods so that feels close.
Looks like they have offered the M235 with better stock engine/oil cooling.
If I was in the market for a new car the M235i would be it, but it is not enough to make me give up my 135i.
