I love the older (early 70s and older) Midgets.

In my personal opinion, the later Midgets are to be avoided. It's been so long since I messed with Midgets, I don't remember the precise year they took a turn for the worse. At some point in the 70s the MG engines couldn't keep up with emissions standards, so they switched to engines and transmissions from the Triumph Spitfire. Others may disagree with me, but I wouldn't touch one of those later ones with a 10-foot pole.

A rust-free MG is a wonderful thing. I would go for it.
