Nice to hear I'm not alone!
ATC's are my biggest love too for some reason. I have three in my collection at the moment, an 84 200ES (in restoration), an 83 200E and their baby 83 ATC70. I'm also restoring a 350X for a friend and have also his 84 200E in storage. I would love to own an older 110 and a 250SX too, if I ever manage to find those! (I live in Europe, so it's not easy to find 3 wheelers here...)
Just got my first 4WD quad, and that is a 1990(I think...) Suzuki LT-4WD. Got a great deal on it, and I think its 4WD system is better than on any Honda!
