Duffer,
We will keep our fingers crossed for your relocation we lost our last spa yellow a while back and it will be nice to have another! There are a few of us on here that are active (about 8 or so) and there are several others in town but they are not active on Prime.
On the first Saturday of the month we have a local cars and coffee meet up which draws anywhere from 200- 300+ cars every month, we have been going at it going on 3 years in Dec (not just NSXx but other great stuff to look at too) Check out the website
www.carsandcoffeecharlotte.com. I post it here as a reminder in the SE section each month.
As far as service there are a few options but one may be out of the game for a bit. My number one go to is in Raleigh who is Steve Gooding. You can do a search here and you will see a number of area NSX owners including myself who rave about his service. He is a Acura Master tech who worked on these when they were introduced and a number of years after in SoCal and NC. He now does it in his home shop in Raleigh. He is taking some time off form turning a wrench right now to recoup from the down real estate market but we hope to have him back soon. It is a haul from Charlotte but worth it.
Also at the local Acura dealership, Hendrick Acura they have a service manager Brian Teague who is very familiar with the NSX and a master tech Eddie who does good work. They don't see a bunch of them but bare with them on the pricing they have to be creative, but you can haggle with them.
Also there is a independent shop ARH Design in Huntersville (north of the city) that is owned by Adam Heglar that has worked on a number of NSXs and other exotics and does a nice job. He is very up to date on his info. So there are a few options.
PM me if you want to exchange info when you get here and I will let you know when we meet up. There is a very large group of NSX owners in the Raleigh area and once a year we meet up on Greensboro (half way) at Foreign Cars International to hang out for the day. It is a lot of fun and we can draw about 20-30 cars on a well planned out trip. Lots of good people and great facility as well.
Good luck and hope this helps.
Michael
