This is the 2nd Silverado I have had. The new one is merely a lower mileage upgrade with more warranty. It is a great truck with no real huge problems except... the linkage in the tranny doesn't drop all of the time when you come to a complete stop from about 60mph. Also, the stock tires throw rocks like crazy!! I am a die-hard chevrolet guy though and this is the price that you pay for being brand loyal. I think overall, the truck is a good buy but just make sure you purchase the extended warranty if you are planning on keeping the truck. You won't regret it when something fails on you.
Definitely the Bose and the XM. But more realistically, the 310hp H.O. 5.3L that gets 21mpg on the interstate at 72 mph with the 3.43 gears.
Get going on a better transmission. Why is it that the consumer has to baby it to make it last?? I want something that is "BUILT LIKE A ROCK"!!!
