The Tahoe is a great vehicle, we just purchased one and have enjoyed it thoroughly. We took the LS upgrade, with the upgrade engine, side impact bags, 6 disc cd, gear ratio and third row pull out. This is a great car, but do your research prior to buying, use this website thoroughly.
Inside options are awesome, makes driving fun and easy, love the OnStar and hands free cell phone option.
Minutes for the cell phone are a little pricey, so prepare for it. Fuel economy is not so great either.
