I like that S10 too....Very similar to mine, but I have the ext cab and the 4.3L. They were cheap trucks and most of them didn't survive well between abuse and misguided modifications (like those Caddy tails), nice ones are getting pretty scarce now....and prices are starting to creep up a bit. Funny enough, I had some same rims on mine at some point....Boss 304's, they were very popular in the mid 2000's mini-truck scene.
I'll be watching that DTS on BAT, just for interest sake. It's clean, but the underside has seen a lot of salt in it's 34K miles. Not a fan of the light tan interior either; I am bias, but when it comes to a big Caddy like this, black on black is the way to go. GM got cheap towards the end of production (2010/11 I think) and dropped the availability of a black headliner, which is unfortunate.
