I was in the same place you were a while back, wanted something smaller, easier to mod, cheap and fast. Bottom line, i know s-10’s like the back of my hand, theyre easy to work on. the motors are strong as fuck, they last forever and they take to boost like a fat kid to cake. not to mention the aftermarket for the s-10 rivals that of the DSM.
If i were in your shoes, id keep it, you got a smaller(ish) vehicle with a damn strong motor in it. Some overhaul of the suspension and it would be perfect to autoX, some motor mods and mild boost and youll be pushin over 450+ HP. Its your decision, but i wouldnt sell the truck, your gonna end up regretting it.
