I sat in my buddys 2006 Grand Prix Gt and there
was no head room. Im 5'11 and my 2002 Gp Gt has plenty of head room. The 2006 Gp has no driver head room. Why did GM do that???????????

Not sure what you mean? I am 6'1" and I have plenty of room, the only problem I have it I have the seat back so far that my head is beside the upright post between the front and rear door so I have to be careful since that creates a pretty big blind spot on my drivers side

They took the head room away in the newer
2004 and up Grand Prixs!!!!!

I don't know what your talking about too. I'm 6'4... Maybe you have more body than legs I guess. Or maybe your not positioning your sit correctly so you do fit.

I have an 01 and I've driven several 04+ and the headroom does seem to be slightly less, more so in the back seat. I guess its the price you pay for a sleeker roofline. Its not so much to make things unusable, just a slight change. I'm 6'3" and I can still sit comfortable in both cars.
