Med Blue or the Light blue are very very nice - my daughter wanted a C10 that was light blue/white that was on a car lot (though is was in rough shape and wanted WAY to much for her).
I suppose I did okay on mine then, I paid 15k from an owner down the road from me in Buda, Texas. Other than yours being Super, our base options are similar. But I have put ~10k into her since last April. Mainly for the rebuild of the SBC 350/TH350/AC - though I have done a *lot* of little things that add up REAL fast LOL.
Edit:
Oh, my odometer was reading 94k, which we are pretty darn sure it hasn't been rolled over. While the engine/transmission leaked, the internals were in really good shape for their age/milage and never opened up before. Which my brother (my rebuilder) was really surprised with.
