I actually was just browsing CL today and found a rolling SI shell with no rust for 300 bucks, quite a deal. I'd be building up this car for my boss at EcoGeek, since he wants to rep the hard core mileage and dress it up in his logo and what not, so I'd be building it for him. Of course, cost is a factor. The d15z1 I'm buying is for myself, and there will be a full write up on here about it,
