2004 Pontiac Grand Prix 2004 Grand Prix GTP Supercharger Qu

Engine Mechanical problem
2004 Pontiac Grand Prix 6 cyl Two Wheel Drive Automatic 72xxx miles

Im buying a car and its a 2004 Grand Prix GTP Comp G.


Although, the supercharger is out they think. They just say that the supercharger knocks when the belt is attached to it. Now does that mean it needs a new supercharger, or a new snout, or new bearing, or does it just need a knock sensor, or is detonating

they just said when the belts on the supercharger the supercharger itself knocks.

The car is only $3300. Kbb is around 8k so its worth it but. Im lost to what to do.

Thanks.
