I would be surprised if your small 135 doesn't feel pretty potent in comparison to the M3.
By the way, congrats on the beautiful car!
I just moved from a 135 JB3 to am E90 M3 two weeks ago. The M is getting more fun to drive every day. It's a totally different way to drive compared to the 1 and quite a but more satisfying. It's faster than a lightly tuned 135 but not buy much.
