Re: Fluids and maintenance - adds value?
It depends on a number of factors. I saw a cheaty Civic (I would have paid $1000 for it just for the drivetrain) get 0 laps because the suspension and brakes were crap. The judges basically said that it didn't have a chance of winning so they swallowed the "I got a smokin deal on the engine/trans" argument. They did put that one up on jackstands and give it a good going over though, so if your car looks fast, then be prepared to get extra scrutiny.
I'm pretty sure that if we showed up with a 1965 Plymouth Belvedere, then we probably wouldn't get looked at too hard, but we show up with a cheaty-looking Civic, so we keep our documentation in order.
