I work at a GM dealer... within a day of each other I took in on trade a 1999 loaded GTP with 190,000KM(my current car) for $1000 and a 1998 GP with polished aluminum wheels from a 2004 GP GT for $1000 also... it had 140,000 KM... I swapped the wheels and now I drive the GTP with the 2004 Aluminum wheels... looks different.
