Thanks for all the advice!
Thanks very much for all your advice and comments. You confirmed what I believed and will continue looking for a 123 or 124 body, although I haven't ruled out a 190 or a BMW 318.
She is my only child and I don't want anything to happen to her! My wife is a high school teacher and we hear about many teenage accidents. It also doesn't help to live in the "Land of the ancient drivers", Tampa Bay!
Where might I find a deal on a good used Mercedes or BMW? The dealers in my area seem to want a small fortune for them.
