andrew - I think you have gone through cars more than I have gone through pairs of pants the last few years. J/K
IMO - the 3-series sedan looks better than the coupe. As others have stated, the 135 is very nice.
Personally, if I was in the market for a nice sized RWD coupe, I would be hard pressed not to go with a new Camaro SS.
I would say to try out a lot of different things, something you were not considering may surprise you. Good luck.
