Hi All, I just started learning about the mini truck world and I'm trying to narrow my focus on a particular model. If I did my research right, I need one that is at least 25 years old so I can register in the state of Connecticut. In looking at auctions, I noticed different designations of the 1989-1991 models. I was hoping that someone can help me identify what these mean: HA-3 vs HA-4. Is this 2wd vs 4wd? I see "models" of: STD (Standard) SDX (Super Deluxe) TOWN (More Comfortable) ATTCK (For farmers) AT vs MT is automatic vs manual transmission so I'm good there 660cc vs 550cc is the engine size so I got that too Does anyone know what options were available between the STD, SDX and TOWN models? I have been looking at pictures of vehicles for auction and I can't really tell.
