Just bought a used 2015 chevy Colorado recently. I have a question if anyone could please help me.. Is it normal that the engine says it has almost 4,000 engine hours on it.. But only has about 55,000 miles.. ?? Something seems fishy. Let me know your thoughts. Im pretty sure ive been had and sold a straight lemon.. Carfax report seems fudged.. "Fleet vehicle" sold and bought from online auction come to find out. Guess from what state... Texas. There is rust inside the cab under the dash.. And the entire underside of truck is rusted. Dealership said its " normal" . i beg to differ. As soon as i figure out how to post photos on here I will.
