I thought they used the 3.1 and 3.3 in the minivans, and now the 3.4. It would make sense, seeing they're all about the same engine (along with the 2.8) because they're 60 degree blocks. The 3.8 is 90 degrees, and I'm sure if GM could they would but that engine in the current ones to make it more competetive.

Anywhoo, those first Lumina APV's and everything were very ugly. Then you compare it to the aztek...progress!
