I'd let a general shop do the tires, that's about it.
First of all there's the "learn while you earn" aspect where the inexperienced tech tries to get up to speed on the procedure as it applies to an NSX.
Secondly they just would not have a wealth of practical knowledge of how NSX's behave. I just looked at a thread where a forum member wants to reset the remote on his keyless but his hatch light is on when the hatch is closed and locked. The majority of the fix responses say to replace the car battery, I wonder how many parts an inexperienced tech would throw at the car before getting around to replacing the battery?
There are many unique aspects of the NSX starting with how to correctly open and close the doors and hatches and it goes on from there.
I just don't want anyone working on my NSX that doesn't know sh*t about them. I'm very lucky to have Brian and Justin here in town at Source 1 to help with my car, then a good friend who is also a certified NSX tech and then I have me.
I'm comfortable with those 3 layers. To allow just anybody- and especially somebody that has not ever touched an NSX before- to work on my NSX? Someone who will shut the doors with the window, drop the hatch or dent the trunk when they close it with both hands? Someone without a service cover for the rear?
Nope...
