I foolishly sold my 2001 Sierra 1500 last year since my house needed some expensive repairs. The market was wild then and it still appears to be wild. I bought that truck in 2016 for $6000..... I sold it last year for $6000. Truck served me well and paid for itself. It's amazing what a few years does with these trucks. Since 2016 these GMT800s either increased in value immensely or completely rotted away (rust belt).
I don't have a desire to daily commute in a truck. However, I always had and always will want an older truck as a second vehicle for various projects and it is nice to have a 2nd vehicle when the primary vehicle decides not to start one morning (doesn't happen often but it has happened).
Living in the rust belt of CT, cheap and dependable are almost non-existent these days. I may need to extend my search area.
I don't particularly need 4wd. My Subaru gets by just fine. I don't need an extended cab.... however, if I decide on a smaller truck like a Ranger or S10 then the extended cab would be nice.
When it comes to these types of questions, I feel most people just speak on the drivetrain to gauge dependability. That is of course important but people forget to speak on the items that will most likely bite you. Things like having to replace a heater core, intake manifold gaskets, blender door motors etc. For example, my father also owned a GMT800 (Yukon). His heater core went out and that was a BIG and expensive job. Other manufacturers made it easier to replace the heater core.
Based on my searches, vehicles that come to mind are one of the Big 3 fullsize 2wd V6 trucks, Rangers, S10s, Dakotas and Frontiers.
If you needed a spare vehicle (truck) in either the compact category or 1/2 ton category for under $10k (hurts to say but the $3-4k days are over for something somewhat dependable) which would you purchase?
