In the S13, leaned back passenger seat and tried right side up. Tried again upside down (head toward floor board). Tried back seat sititng on him. (worked but not fun hitting head on roof) Ended up in the back seat. It worked just fine.

Fold front seats up and push them forward. Had couple shirts for a pillow. lol Might been a different story if the strut bar wasn't in the way. Just fold the back seats down and get in the hatch.
Proved it in the Plymouth Laser I had. Leaned back the passenger seat and it works.
