Well I did it today. Went and bought a 2008 Tahoe Hybrid. What a SUV this thing is. Great ride, plenty of power and decent mileage. This thing should get better mileage then my 02 GMC Envoy. I like the Envoy so I'm going to hang on to it. I'm going to take the Tahoe to Idaho late next month. this will give me a good chance to calculate the MPGs. Will report after I return.
