2007 Chevrolet Tahoe

I purchased a 2007 Tahoe in May of 2006.I chose to go with the LT1 and add the upgrades I prefered.I opted for the wheel and tire package, 4x4, bose sound system, and the larger engine with towing package.The dealership gave me an additional $1500 off of the price because this exact Tahoe did not have leather like we wanted.Sounds great, but for over a year now it has given us some problems like a month after we purchased it, the "check air bag" light came on.Evey once in awhile, the driver side window controls will not operate the front passenger window.Alos, I was fishing at the outer in June 2007 on the beach and he four wheel drive went out.Other than the electrical problems, I think it is an okay buy, but I wuld like to see the price go down.
