Does JPS advertise their speedsters and coupes as "used VWs" on their website? If not, why would he even have the balls to make such a statement to someone who has bought one? Anyhow, is he saying that he uses used VW parts to complete his tube frame cars? I'm sure that if this were advertised to potential buyers, they would be a little more apprehensive to shell out that kind of money for a handcrafted automobile comprised of used VW parts.
In this particular case, what would the "other side of the story" possible be other than excuses? A quality hand built automobile should be one that the craftsman takes pride in, not one that he avoids. Every effort should have been made ensure that the car was an example of the craftmanship that JPS has to offer. Or perhaps this is a perfect example of the craftsmanship that is offered.
