1997 GMC Yukon

My husband bought a used 1997 Yukon on Ebay to pull our boat. For the most part it has fulfilled it's purpose. Unfortunately the gas consumption was insane. Most of the time it got 12 miles to the gallon. Our other vehicles get in the 30s. Other problems we had included an unreliable air conditioner and brakes the frequently needed repair. This is the only American car we've ever owned, and it is also the most unreliable car we've ever owned. But once again we only bought it to pull our boat, so we really didn't use it that often.
