Jon, I love looking at her... partially because even if she isn't the one I sold back at the start of the 90's she is a close duplicate. The one I sold was one of the few "flips" I ever pulled off, I did not own it for long and didn't get to drive her too much.
Mine was actually acquired by my parents for some strange and unexplainable reason. When it eventually got to me, it had been beaten down by my mother, who drove it with a leaking transmission and refused to keep it topped off. I don't think a non-numbers matching transmission would be a very good identifier.
If you ever trace the title history, let me know... maybe I can fill in some gaps is it's the same car. The guy I sold to loved the car and was kinda famous for buying them with low miles and keeping them low while giving them the best of everything to keep them looking good and running right.
