I had my NSX as well as several of our customer cars done by RJ Vintage Garage. The owners name is Ron Wilson. I'd highly recommend him.
He knows the cars quite well (which is rare for an appraiser who do mostly classics). He will come right to you.
Great service, very friendly and very complete. He prepares a full 18 page colour document going over every aspect of the car and photos for your own records/ insurance company.
You can give him a call at 705-878-2372. If you need a nice warm indoor place with a hoist for him to inspect it, feel free to use our shop if you need Tommy.
