I've seen this shell many times as it sits behind a business and it always was right side up and looked like it was just there for short term.
It's been a couple years since a checked on it and today I went to look and not only was glass broken out and it was upside down, but upon further investigation I was even more disappointed to find out that it's for a full size truck.
I never got close enough before to know.
Bummer.
