For what it's worth, I've done toe alignments in my driveway a number of times. Google the "string method" for more details. It involves running a string around the whole car to measure toe and using glossy magazine pages under the tires to allow them to turn easily, so you can adjust the tie-rods. I've done it to get my car to the dealer, and found it needed 0 adjusting once there.
edit: FYI, on a stock e30, toe is the only thing you can adjust.
