I did pay up front for the drawings. I think I paid $3200.00 for them. Dave was in the process of finishing some detail and assembly drawings. So I waited and waited and waited. He also builds the tubs as well as other cars. He's a busy guy. That I believe was the problem. After about a year and half of waiting and still not much to work with I decided to go a different route and he refunded my money. He's a nice and smart guy. I don't know if things have changed regarding delivery of any drawings. So, I can't comment on the quality of the drawings since I never really got to see any.
