The roadmaster shouldn't be on there.
I'd replace it with the Toyota Previa. Supercharged mid-engine/RWD van? What?
The motors are layed almost all the way down under the drivers and passenger seat too, it's almost half a boxer. It's got a shaft that runs to the front of the van where all the accessories are driven, so your alt, a/c compressor and p/s pump is all up front still. Plus the two sunroofs are funky and before their time. Same goes with the ice box on the floor.
