I ended up buying Grand Prix a few months ago at the behest of some on here. Well, I didn't actually get around to watching it until last weekend. Wow. That movie has some of the best racing footage I've ever seen! The director did a great job of making you feel like you were actually in the cars. Especially that one race in the rain. I kept trying to move my head around to see better. (Like that was actually gonna help
)
I also finally found a copy of Days of Thunder. That one was hella hard to find for some reason. Days of Thunder was ok. But not near as good as Grand Prix.
Thanks again to those of you who suggested that one.
