I spent alot of my childhood in the back of my mom's 70 Mach I. It's a great place for a little kid. When she had too many people in the car, my place was up in the back window with no place to look but up. lol
Haha! That brings back memories of the back of a family friend's Bug with #2 other kids and me in the area behind the back seat!
I grew up in the back of my Dad's 1965 Coupe. He installed a cute little pony seat belt in the back, just for me...but he didn't put it there to keep me safe. He installed the seat belt to keep my feet off the back of the front seat! I also was never allowed to touch the paint on the car, unless I was helping him wash it--the microdust on the dry paint might scratch it if I put my fingers on the car. I learned all of my swearing skills from him, working on that "cold blooded %#%^$#*&$@er." Ah, the good old days, LOL.
