Yep before they became fullsize...
They sure did. I had a fleet truck get totaled and the insurance gave me the first Colorado id seen for a rental. Was nearly as big a the gmt800s we were using. Had a 5 cylinder that I thought was perfect for a car. Great top end. I don't know if they ever used it in a car though. I never saw one if they did.
A lot of these though, sport trac, s10, and Gladiator are body on frame. May be competition. Maybe not. Idk. Ridgeline, baja, Cruz, Maverick etc are unibody.
The Gladiator (i have a Rubicon) is a terrible handling, riding and driving vehicle that is perfectly at home offroad. It may be direct competition but the over lap has to be minimal. If you want to go offroad then the Maverick and cruz (or baja) don't come any closer to the jeep than a Mustang or camaro would. Other than a g wagon the locked front and rear jeep is probably the most capable vehicle made now. A foot of ground clearance and the tires mounted on the farthest extremities give it approach and departure angles that are not possible with anything else . I can't imagine anyone narrowing their choice down to the Gladiator or Cruz. Seems like narrowing it down to a prius or a corvette.... both 2 door but that's about it. Most Gladiator I've seen cost as much as 2 maverick. My f150 feels closer to the Cruz than my Rubicon does. By a lot. My wife and dad both refuse to even drive the Rubicon. Lol. Hard to compare any vehicle with a front straight axle to one with independent suspension. If I were taking mine to California to wheel again....id most likely pull it there rather than drive it.
I've worked on several sport trac. Never had any desire to get one. They had the 4.0 and 4.6. Both great engines. Probably offered others too. Nothing spectacular on power. Even the 4.6 was barely over 300hp. Many 4.6 police/ taxi etc and mustang/f150 are still on the road over 300k miles. They shared a lot of parts with the f150 too.
Every true 4 door s10 I saw had the 4.3. Great motor but I never saw one get decent mileage . Even in the little blazer. About a billion of those still on the road too.
