First GM product I have puchased in 30 years. I've driven a 97 Land Cruiser since it was new and it's still going strong with 160,000 miles. I will say the Tahoe has a tough act to follow, but so far so good.
Interior layout and comfort. OnStar pretty cool but then it's new to me. I like the 20" tires. Exterior looks great.
I haven't had it long enough but I'll find something that I don't like.
