  1. Think back, 2003. A lot of people bought Yukons and Tahoes because they were designed to do what we needed them to do. Today, they are 6” wider, 6” longer and the rear seats do not fold flat. At 210,000 miles I will be replacing mine with a Toyota because GM can no longer make a vehicle that suits my needs. I would love to just go buy a new one but, sadly, I can’t.
