Buying a 99-2003GT so I have a few questions.

The backseat isn't really smaller, but you have less headroom. On the Fox, the roof is flat, so the people in the backseat have the same headroom as the driver and front passenger.

On the SN95, it has a curved roof and it begins to come down right where the backseat passengers head is. I'm 6'1" and when i sit in the backseat of my Fox, i fit fine, but when i sit in my '03 GT, i have to tint my head to the side.

Nobody sits in my backseat anyway. If i ever need to take 2 passengers, i use a different car.

A snowboard should fit. WIth the rear seats folded down you have a good deal of room. It should be as much as the Fox so if you could fold your seats down in the fox and fit it, it should work with the Sn95. I've fit a bunch of things into my car. A bike, a wheelchair, 2x4's. etc.
