Why an auto ? Is it a choice or a necessity ? To be honest, given the option go for a manual or if you want one that actually moves, go for a T.T.
If you read through the GTO forum on here, i have probably hilighted most of the issues with these, if not, you are welcome to p.m. me and i'll give you my numbers and i'll gladly talk to you about them.
