I went to look at this truck wednesday and looks good all emblems engine runs good ac is cold looks like original owner lived on dirt road frame a clay color but no undercoat looks like LR and RR cab only bondo I could find paint is gone looks like someone painted and crossed primer brand with another paint brand dry lake bed effect.My question what is a good price? And anything else I need to look for? I did check the vin so it is original as far as engine and auto trans.
