Depends on WHICH GL you are talking about. The EA-82 powered cars came in 3dr, sedan, and Wagon. EA-81 cars came in The hatchback, sedan, wagon, and brat. Before that they came in a variety of items, but they are fairly rare now. (anyone want a 70 or 71 subaru FF1??)
The 3dr is a real sack of crap unless its a 88 or 89 RX. Get a XT if you want a 2dr car.
The Hatch is the best of the old 4X4 cars as it has NO overhangs compared to the others. With a little work a 5spd Dual range bolts in, and liftkits upto 10" have been made. 4" is the common lift. Many people run 27" tires under thier cars, but I have heard of upto 31"s going on after a bit of time with a air nibbler applied to the fender arches.
