I've been lurking for a bit, we just bought our frist Grand Prix this past week. Found a Dark Blue 07 GXP with 32k on it. It is replacing a 2003 Buick Lesabre as our daily driver. Been a fan of this car for a long time, have looked at buying one in the past but it just hadn't worked out.
Seems this car has had a few toys installed at some point, then removed. When I got it, there was a pair of Pioneer interface boxes under the dash not attached to anything with cut wires.... ugh... But the GM head unit was in place with no cut wires. There is also a monster cable under the hood, so at some point in the past it had a stereo system in it. Nothing is hacked so that is a plus.
I'm a gear head and love LS engines. Looking forward to plugging in the wide band and logging some data on the GXP and see if I can gain a little performance over what GM slapped at it.....
Looking forward to reading and learning from you all.
