The cars I've seen most in the Kingdom Hall parking lot: the familiar, dull 4-door car, the family minivan, or the old beater. Sometimes the occasional 2-door car, which was generally frowned upon for service. I don't recall anything particular flashy, like a sports car, BMW, Mercedes, etc. Of course there were some nicer cars for families who were better off financially (translated: those who actually went to college and got a degree). Those were usually the ones that drove in service.
OK, let's hear it... what kind of car did you drive when you were a Dub?
I drove a '79 Olds Cutlass, an '85 Honda Accord hatchback, and a '88 Honda Accord. All 2-doors, too.
