i saved my money 2k banked for repairs in the last year i only spent $489 on a couple of sensors and brake job in 14,143 miles..
Don't you have a GMT900? Those are far better trucks (in my opinion) and much cheaper to own. I would say pass on the warranty for a 900 but not for a K2XX. Maybe pass if it’s a strippie base model but heck that electric steering gear alone will set you back $2k if it fails.
