I recent came across a pair of 1991 Lumina Z34's on a back road here in town and they are going for $1500 for the PAIR and one of them is a 5 speed.

Makes me wish I had $1500!
the 5speed car is pretty rare.

A friend of mine had a 5 speed Z34 in high school. It went through a LOT...

Those twin cam 3400s were a scary ordeal, though...

I had a 91 Grand Prix with a 3.4. It was a good motor when it ran right. That just rarely happened. It ran great cold, but once it warmed up, it felt like it lost 50-75 hp. I never could figure out what was wrong with it- Good compression, started fine when warm, converter wasn't plugged, didn't use oil... The check engine light was on once in a while, but would only give me the speed sensor code that is standard when the car isn't moving when I went to check it.

Anyway, I always wanted that car with a 5 speed. That's an awesome find!
