Bruce: Your inquiry into Specialty Autosports will undoubtedly result in a number of comments mostly from people who do not have a car from them. Charles Gardner is the most reliable source of information as well John Hallstrand, aka Hoss. I have a SAS Cabriolet and have met Charles on numerous occasions. His coupe is by far a better vehicle in quality, performance and mechanics than the original. I will not comment about JPS or their coupe but would refer you to Tom Dewalt's comments on his JPS coupe. SAS has it's positive aspects and it's negative ones, however, the negative ones are not about the quality of the vehicle or support by the builder. The negatives are in the time from day of contracting to the day of delivery. Oh, BTW, Paul Robbins, a California TV personality, has a SAS Speedster. A caveat from Paul's experience trying to register his car in California is that it is easier to register the car in California as a used vehicle with a Tennessee title. Also interesting is that all SAS vehicles meet Emission Control standards.
