Here are my thoughts. I have nearly 67k on my 5.3. the "leather interior" is a complete joke. first of all, the seats are leather, but the arm rests are not. have had to replace the driverside once and it needs to be replaced again because the material is cracked again. my best guess is they replaced with with a vinyl instead of leather because it was cheaper. $250+ labor if i want it fixed again. also, the dash. i know a few otehr people here have said it looked cheap. how right you are. the orignal color of the dash is black plastic, that is painted to match the interior of your truck. i know this because the pain stated peeling off resulting in $200 worth of repair work.
i have none. even onstar is a joke.
Buy a toyota, get out a pen and paper and start taking notes. the 2008 Tundra has the interior, the exterior, power and gas millage that we all want in a truck. not to mention leg room. my advise to chevy, scrap the silverado and start from scratch.
