Hey Guys, I have an opportunity to buy one of the 137 2015's produced. Track package Avalanche Grey car. Under 5k original miles. I have been researching and following these cars for the last 12 months but mostly focused on 2016 MY and newer because all of the 2015's that I had seen listed were asking crazy money. That being said I am very interested in purchasing this vehicle but would like to know what you guys thought? Is there anything I should be concerned about? Reasons TO purchase or reasons NOT TO purchase? I plan to actually drive the car on a consistent basis. Lets hear what you guys have to say!
