Hello; Back in the 1970's Opel made a car, the Opel GT which had a closed back end. A buddy had one. No trunk opening. He had to get to the space from behind the seats.I don't see how this is practical. I think it would in a pain in the butt to get the wheel out through the main cabin unless the trunk opens up and you can pull it from the back
Sold on BAT for 67K someone liked it - alot
Not to mention how would you get the seat belt around the grandkid sitting on the tire.I'm old enough to remember the Opel GT.
And, no way would I want the smell of that tire...fuhgeddaboudit. :-)
