[M235Montreal]

Greetings Guys!
Am sure lots of you have been asked these question before but please allow me to ask it in a more detailed way.
First of all , am about to make a move a go for a CPO bimmer this Summer and it's gonna be most likely the 335i, so i want to know your input on the Following:
1) do you regret getting a 335i and now think you would've been better off with the 328I? ( reliability issues)
2) if you own an Automatic! do you regret this choice and wish you had a Manual?
3) if you Modded your N54. do you regret this move ?
Thank you
