I know Doug has done it, but I've been reading a bit into it. I'd like to do it. 500 dollars is a slim budget. Non title cars seem like a risky bet, but it helps lower the price, and blown head gasket (assuming there's no cracks or warping) is a reasonably cheap fix but also sort of risky since I don't really know how long it's been driven like that. Mostly around here there's a couple grand prixs and a couple old buicks on Craigslist. Some sunfires. I'd like to find a shitty 90-93 Accord or a bombed out EF Hatch. Seems like the whole race would be a good time. I have a friend who is a certified welder who could do the cage. Anyone have any thoughts or suggestions?
