I'm debating whether to sell my fronty. It is a meticulously maintained vehicle with 150,000 mostly highway miles. I'm not sure what to ask for it. KBB is about 7500. The one thing that bothers me is the check engine light is on. The code was for the precat o2 sensor, which was replaced however the light came back on. Neither my mechanic or the dealer can figure it out. Other than that the truck runs and looks very good.
