I've slept in my old Corvette twice. It's not meant for that in any shape or form. I actually laid in the trunk and had my feet going up to the dash in between the seats.
LOL reps! It was drizzling rain and I ended up rolling myself up in a tarp outside and sleeping in it like a burrito. I was at a race track last minute in the middle of the week without a tent waiting for the team to get there. Sucked lol!
