Since it is on a Chevy chassis, if you have a good relationship with a local Chevy dealer, they will be able to look it up and tell you a lot that it has been through. Any work done by a Chevrolet dealer should be in their nation wide system. They might tell you they can't look it up but they can. Just depends on how well they know and like you. Any warranty work and any major repairs should be on their system.
