Wicked is good, I just had my car tuned there. At an hour and a half of a drive its a bit far for maintenance and things.
I've also been really happy with Alberto at Motive Auto Works up in Woburn. It's a much shorter drive and he does great work. Alberto's waiting room is pretty solid too, nice couch and a **** load of DVDs. I've nursed a hangover in both. The window at WI is pretty cool though.
