Seriously though, what is the life expectancy of one of those chassis, 1 race, maybe 2?? Maybe thats why racers get away with sins in welding process that would never last in other avenues. I have co-workers that have come from GM and Ford's engineering group, and they all aggree that the performance end of those companys can teach a lot about performance, but little about lifespan.

A lot more than that. And you can buy retired NASCAR chassis for personal use for pretty reasonable prices and run them as long as you want.
