As an aside, there's a couple of sister cars to Jeff, both white as I recall, both built by the same group of SPS racers/GM engineers. They each come up for sale every year or two. If you REALLY want to race a Saturn, you're saving yourself scads of time, money, and hell by buying one of those as a start.

Greg's totally right on this. I knew Jeff's car well before Jeff had it; I crewed on that team, know the engineers who built it, and you damn well better believe it cannot be duplicated for any price.
Except buying. Which you should do. Chris Berube's car is still for sale; it is one of those aforementioned team/sister cars to Walker's old car, aka Jeff's car, the red one. I can hunt down Berube's contact info around here somewhere - I remember seeing the posting on the walls at Milford, sure we can still find it. You'd be far better off buying Chris's car and parting out your car, if you've got that big a hard-on for a Saturn.
Note that the cage in those cars was designed using the original GM CAD files for the chassis - it's second to none. Just like the inside access on tuning the ECU.
This is as close as any of us can come to affording a factory-built factory team racecar. Even if it is a Saturn!
Oh, for the record, as one of those who built my own... I had guys like Walker (who built Jeff's car) advising me down the right path. Yes, I built the car that I had. But I almost immediately scrapped it for a better candidate of the same model. While it was hopelessly outclassed (being an ITA car at the time), it was at least a perfectly solid car for the track, being a Porsche.
The SC2 is NOT. Even when fully prepped, it requires vast amounts more maintenance than the Porsches, when both are run at the pointy end of the field. Things like bearing wear (I repack mine every year, change them when I feel like it), brake wear (no new pads more than once a year), engines (going on 5 or 6 years on the same build, my own), shocks etc... I'm sure Jeff can provide the counterpoints in detail for the SC2, but I know from firsthand experience that pads and bearings are lucky to last more than 2 weekends on that car...
