If you are considering the switch to a F8X or M2 Comp I would HIGHLY recommend a DCT example. Not only will you pay less but it is ABUNDANTLY clear that the power delivery of the car was designed specifically for that transmission.
FWIW I think the F80 M3 is the best looking M3 ever made (quite a bit more muscular looking than the F82 M4) while the M2 Comp is basically a modern turbo-charged E36/E46 sized offering.
Either car will likely prove much more reliable than the E9X platform, especially if you leave them stock…okay MAYBE change the brake pads to a set of Ferodo DS2500s
FWIW though…I was fortunate enough to own an F80 and my E92 for about 18 months together.
Once my lease was up on my F80, I decided that the E92 delivered enough thrills for me and was more rewarding on the track…on top of sounding like an exotic.
I do miss the "watch what you're doing or I will kill you and laugh while doing it" tire destroying hilarity of the F80's S55 sometimes though…
