I'd go to a cruise-in on Friday if you were closer. I'm in north OC.
I'd definitely go to a show if it was a weekend with other vendors, your local retailers, maybe some swap meet type spaces for locals in a back lot. You need just a little more dangling of the carrot than a factory and show cars.
My impression of an upholstery factory is a bunch of sewing machines and large rolls of of vynyl...invite California Mustang and have them do a co-op, bring all their clearance items and tell them to discount their prices for space at your show. Any other retailers?
Come on, man! Go big or go home (I know, that's lame). But seriously, you gotta do a little more to get the OC/LA crowd to drive down to the dust bowl on a Friday night. None of us want to sit on the E/B 91 on Friday night! Holly cow, that's horrible. You'd see 20 overheated Mustangs on the side of the road now that I think about it...just say'n.
Yup, better make it Sat and pay some peeps to work some OT on the weekend.
BTW - I love TMI products, even if I never see the factory.
