It’s too bad there isn’t too much web traffic on this forum otherwise you might be able to gain momentum and get this going. If you’re serious about setting this up you will want to post in the socal subforums on many of the other sites like F-chat, nsxprime, 6speedonline, honda-tech, etc etc etc…
Btw… doesn’t Pep Boys have store hours on Sundays? I really wouldn’t want to attend a car show where the parking lot has to be shared with regular shoppers. You won’t really attract the garage queens if this was the setup imo but that’s just me…
good luck!
