excuse me??? you are the one here asking for guidance and now you tell us your "small problem". weren't you so very concerned about the cost and maintenence in the first place? first of all, you don't even tell us what your budget is and what you are looking for. if budget is not an issue where all the above toys as you call it are available, then i don't see what the problem is. next time, be more detailed in your request!!
if you have $750K to blow , then i suggest you go for the latest M3. it has all the toys you want.
the only problem i see here is you. you can't decide what you want and want other people to decide for you or to convince you. well, we don't get anything in convincing people what we like to drive...and especially so to people we don't know.
this is not the "don't care if beemer or not" forum.
