I reread this and saw that this is your DD, some of the best advice I can give as far as that goes would be to buy a beater. It doesn't have to be fancy, just something that you can drive if for some reason a project takes a while, or something to drive in the winter so you don't have to worry about some ***hat sliding into your car on ice and totaling what you've put time and effort into.

Which brings me to another point, if you're modding a Grand Prix, make sure one of the first things you do is the transmission. From the factory they aren't made to handle the kind of abuse most of us put them through.
