I believe you should give us a heads up on where not to take your car or where to take it when it's screwed up.
You know it is amazing to me that Acura dealers don't know how to work on the NSX. For example - mine was worked on previosly by the third owner who took it to a dealer in Houston for all service and had the clutch replaced. When I got it the clutch felt really hard to activate. When Barney (barn man) took it down and got to the clutch - which I replaced and flywheel, master and slave, the dealer had used the wrong bearing shaft grease (something like that) - now what kind of a dumbass would do that when the proper Honda grease should be right on hand - I mean give me a break. Had the proper grease been used the clutch would have lasted a while longer it had 40% of it's life left.
So I share your pain! Make sure you get the right mechanic on your NSX - to all out there contemplating just taking it to the dealer! Be careful about selecting the right guy!
