HAHAHA, 6" guy. im about 2 months out from purchasing myself hopefully a 2010 S. I find this thread a great read due to the fact i havent sat in a G yet but want one so bad i hope it fits me. 6'2" 260lbs body builder frame. big legs. pants are 38"x36". fingers are crossed, but if i dont fit ill prob just force squeeze in.

 

OK a few things (coming from someone who is 200lbs and 6'3"). It's all about torso length and seat angle preference, not height. I have seen people who were 6'6" say they fit fine, I know that my hair brushes the roof at times and I have to recline the seat more than I like.

If the seats are too narrow for you (just fine for me, but I'm a leaner build) having the side bolstering adjusted may be an option. If you don't fit due to headroom... don't buy the car lol. It's not worth it to have a DD that you aren't comfortable in. It just isn't.
