Ok, since this is a consignment sale, the dealer should call the seller and ask them exactly what the car has.
Likely it has a Stage 3 exhaust if you start it up and it "rumbles", and it sounds like a sport bike at high revs while driving. It should also "pop" and "gurgle" on shifts and deceleration. You should barely be able to hear the supercharger if at all. Should be a single oval tip. A dual tip is likely a Stage 2 exhaust, meant for non-supercharged cars.
If it has a stock exhaust, the supercharger will be very clear and noticeable. You likely will not hear or feel the cam switch (around roughly 5500 rpms, but varies depending on load).
A "stage 2 ecu" could mean the dealer was told something was done to the ECU, but they clearly didn't understand. There are tunes available, so its best to clarify with the actual seller exactly what there is to know about the ECU.
Consignment sales should be easy on the buyer, as the actual seller is available for contact (through the dealership) for all these sorts of questions. Don't let the dealer answer for the seller, but instead suggest a conference call with the seller. That way they remain anonymous, if desired, and you get real answers.
