I'd have to look at the brand new Colorados to see if they've changed ....but the last used Colorado P-U I looked at ...maybe it was a 2014 (??) looked great on the outside. I was in the buying mode. I 'wanted' to like it because I didn't care for the GM full-size styling (pre-2019's). But inside I was off-put how cramped the Colorado was. Wide console meant minimal legroom, head close to the headliner and top of windshield, couldn't see the speedo well b/c the steering wheel was right in front (at it's most comfortable position ..for me). I'm like 6', 175 ..not overly big guy. But the *absolute worst* issue of all, was the steering wheel was off-set to the right 'juuuussst' more than too much, that it would forever bug the crap out of me. But I liked the Colorado styling a lot more than the full-sized GM's (at the time). Perhaps it was just the seats in the couple Colorado's I looked at. I seem to remember that being the case on the older S10's too. Fortunately they designed in ample driver room in the H3.
So I ended up buying a Ram 4x4 with the Hemi and a bench seat. I'm continually astonished how nice of a truck it is to drive and the little extra design details that make it nice (to me). Mine's the Tradesman that has the old-school xfer case and 'real' 4-high (and low) not the watered down system in most Ram tks. This was a couple years ago. It's been a great pickup, 160k miles on it now.
Hopefully, they've boosted interior space in the newer Colorados because otherwise I like the package, especially the ZR's.
