This was an Early 2010’s Silverado with Duramax diesel engine and holly fucking shit, I have never seen a million mile car in my shop and first time seeing it in person. Don’t know further details how this customer got his truck to a million mile but despite having electrical issues, engine and transmission runs fine and frame is not badly rusted. Unfortunately, odometer maxed out at 999,999 miles and to get accurate odometer, speciality OBD is required to retrieve it.
