Congratulations on the new car!
Here are my recommendations, based on my lurking on this forum and personal experience...
Dealer - Goodson Acura in Irving (great work, but expensive)
Local shop - James @ Accurate Car Care (817-640-4306), he owns an NSX and comes highly recommended for all maintenance, header installs, general issues, etc.
Performance shop -
Jotech is the only tuning shop in town I would feel comfortable recommending. Kenny Tran knows what he is doing and runs a top notch shop! If you go there tell him Jason in the black NSX sent you :smile:
Alignment -
Autoscope, these guys are mainly a Euro shop but they have a very good alignment rack and charge a very fair price for the service. Their facility in the park cities has a drive up hunter rack that is built into the ground for us low cars
They spent 3hrs tweaking my alignment until it was perfect to their standards, I was very impressed.
