I have this 2009 GMC C4500 former ambulance that was just taken out of service. Starts and runs as we just drove it 60 miles back home. All sirens and air horns work. It does and has a lot of cool things that I just don"t know how to work. This would make a great tow rig, camper or work truck. If you have any questions please feel free to ask. I do have the title in hand.
