I guess everyone is different... although I'm only 6' and 175, I wear a 34x36 in Levi's so I'm mostly legs. And I don't have my seat all the way back. But I prefer to sit more upright than some people do so that might make a difference.
I wear a 34x34, so you've got me on leg length but I've got you by more on torso. I have to have the seat lowered all the way down and moved all the way back to have any resemblance of comfort. It's OK, but not enough leg length for me when the seat is low. Any higher, and my head touches the head liner.
I drove an Obsidian Black GS 450h at lunch. Nice car, and I actually fit better in it than in the LC. Only problem is that w/ the seat all the way back in it, it has slightly less leg room for rear passengers. Also, the truck is TINY for the size of the car due to the batteries. Drive and feel is very impressive, but then again, it IS a Lexus. MPG on the interstate was hovering around 28-30 at 70MPH. Cruising around on surface streets (stop and go) at 30MPH was all-electric.
I could buy that GS and sell the LC, and pocket over $250/month in extra cabbage from the lower payment and lower fuel bills... Dayum.
If I did that, I'd still have to have a truck for a "toy", but I wouldn't care if MPG were in the single digits b/c I'd only drive it when I wanted.
If the LC is too small, get a sequoia.
Co-worker has a Gray Platinum w/ the Clay Leather. Nice truck, but it's so damn wide it's difficult to park in "normal" lots.
