I've purchased a 99 rodeo v6 looks great, runs great and clean. 160k. I think it still has a lot of life left in it. I'm going to have it checked by a local shop, but want to upgrade some of the parts. To make sure it's good to go. Only things are the aftermarket stereo wont turn on, I cant get the back hatch to unlock and open, abs light is on but no issues and the left turn signal stays on but it's the lever. I found a replacement. Changing to a synthetic oil? Thoughts on all this? I like this rig. I want to start replacing some components, like shocks, struts, engine stuff if needed, filters, fluids but seems well maintained. Stuff like that. It looks And runs great. Either its a new engine or well taken care of.
