What's the chance of more aftermarket performance pieces coming down the road with the introduction of the new Northstar powered XLR? I was able to drive the XLR on a SCCA type solo 2 road course about 2 months ago just south of Los Angeles. Great fast car, but like anything else, its never enough (well if you're like me anyway). Wouldn't most engine upgrades/go fast pieces interchange with other late model Northstars? Any thoughts?
