Typically, if the problem stems from a Saleen part or system (intercooler pump relay recall, poor fitting c-pillar), then the car needs to be taken to a Saleen authorized dealer.
I
f the problem is related to a Ford part (fogging headlamp assemblies, poor retracting seatbelts, missing rear brake fasteners), go to any Ford dealer.
I did have a problem with the upper radiator hose contacting the drive belt, shortly after getting my car. On supercharged cars, the hose has to be aligned carefully to avoid being cut into by the belt. I called the Saleen warranty department about the problem, explaining that I did not want to drive the somewhat long distance to the original dealer, since there is one a mile from my house. Under those circumstances, back in 2000, Saleen and the local Ford dealer worked something out and replaced the hose (correctly) under warranty. It was a simple fix. I wouldn't count on Saleen doing that in most cases these days.
