Well I just bought a 1991 Toyota Corolla Wagon All-Trac. It has a center locking differential. EPA is 26 hwy, 23 city. Users normally get abut 28 mpg mixed. About half the MPG of my saturn sc1. I'll be happy with 35 mpg with a few mods. I drove it home, 128 miles on 3 cylinders. It needs a head gasket, but I think the plug is fouled also. I didn't have a spark plug wrench with me to check it. The car is from Western Washington and has no rust. It drives good and I got a good deal on it. Pictures and progress reports soon... The previous owner named it Augie for some reason and so the name says as it is my late twin's name also.
