hi..

i'm interested in buying a 2002 mini cooper s with 65,000KM. The car has been moded and i think it has a 210+ HP STAGE 2 KIT FOR MINI COOPER S 2002 - 2006 from minimani.com. Can anyone tell me what i should be concerned with b4 i purchase this car? does it decrease the engine life? use significant more gas? expected yearly maintenance cost? etc?

thanks
