Yeah, those 4-door units were oddities...I like the functionality of them, but the proportions are terrible compared to the regular pickups, or even the Blazer/Jimmy. Looks really clean though, definitely a rare find.
IFGC - 2005 was the final year, they only offered the 2-door Jimmy/Blazer (no pickups, no 4-door suvs), and they did blow them out at really aggressive prices. Similar to your story, I recall a buddy of mine buying a brand new one, straight base with manual windows, 5-speed, for sub $20K. At the time, that was a great price for a 4x4 SUV with the reliable (and capable, for the time) 4.3L.
