I had a chance to compare a SF GT40 and a CAV GT40 on display side by side 30 feet apart at the Cobra Bash in Reno in 2006. I went to both cars and was able to climb in to check fitting in the cockpit of each car. I went back and forth quite a bit to where it was finally up-setting the SF rep. The next morning I was down at the display at 6:00 A.M. to wipe down my own car that was there for the event. It was just me and a guard on the whole floor of 200 cars. I took the liberty of lifting the rear clam shell and stepped into the engineless engine bay of the SF car. I was down on my knees checking the welds at the tub. It looked like a high school kid did it! They were mostly done sub-standard. It looked like some one blew they nose on it and painted over it ( I call these Bugger Welds). I was very concern. I then heard a loud voice say "What the hell are you doing in there? I looked up to see Peter Brock peering in at me! I said I was comparing the build quality with the CAV next to it. He then walked me through several other items on the car, some of which he had discussed with Jim Price at Hi-Tech Auto when he was there doing the Daytona Coupe project that he was concern about. Don't get me wrong, I 'am not trashing SF as I actually own one of there products. After watching the guy welding the panels on the program last night, I see why. It was 4 years later that I had a chance to bring a CAV home. So I guess that earns me a ticket to bitch or praise about both products (LOL)!!!!
