While some of us appreciate both trucks and robust early SUV, many don't. It's two different niches of vehicle. Early Broncos and the CK Blazers aren't even really the same thing, the Blazers were a lot bigger and sold a lot more? (Except the really cool late 70s Bronco which was bigger). Bronco values to Scout values makes more sense.
It also looks like 2wd truck prices are in the mix here?
Trucks you have the 67-72 CK leading the pack for years now. Then Squarebody (maybe not in values but in numbers). The Fords have caught on in recent years, and aftermarket is starting to catch up --but dentside is way more popular than bumpside from what I have seen.
This truck tide is slowly rising Dodge --while being aware that 93-up Dodge is a serious player in the hobby.
Jeep Gladiator pickups were rare to begin with. The market is moving and you have that name brought back. We are surprised these have gone up in value?
Here in Colorado, the Jeep brand has always had a special cachet, and the pickups sold well. Often, Jeep pickups (and Internationals, for that matter), were more commonly seen than Dodges. When the downsized MJ/Comanche (based on the XJ/Cherokee/Wagoneer) was introduced, it was quite popular, posing a direct threat to the Dodge Dakota. When Chrysler took over AMC/Jeep from Renault, they took little time to cancel the Comanche....
The K5 was the best of the group in that era.
The Jeeps are hard to find. They sold less and most the bodies rotted away in many areas.
My dads buddy had a cool Gold and Blue Honcho with the Levi interior. I loved that truck but it was rusted out in 5 years.
Supply and demand of today is driving price.
I miss the heck out of my 1976 Jeep J-10 longbed. My Late Grandfather bought it used in 1978. He gave me the truck in 2003. I did have to put some work into it to make it roadworthy again. I sold it to one of my cousins in 2011.
