We also have a 2000 model with the vents. The Wilwood brakes especially the emergency brake, have a tendency to rattle. The upgrade is a clip that anchors the brakes better and eliminates the rattle. The drivers side CV boot was aproblem for some of the earlier SPF's but not on all. Occassionally the boot would tear and the grease spray all over the upper A arm and wheel well was an obvious diagnostic tool. Look for excessive grease splatters on the drivers side, if it's not there, then there's no problem. Ask if they performed the update on the upper rear A-arm bolts and bushings. They did have an update on our series.
Everything else sounds good. Be sure to check your motor mounts when installing your engine and measure the side pipe clearances on both sides. You don't want the pipes too close to the bottom glass ledge. Is this car coming from a dealer or a private individual?
