I bought my 2015 Silverado new and posted it in this forum when I bought it. It's a double cab 4x4 with the 4.3 V6. I currently have 83k miles on it.
Reliability has been solid, no mechanical issues at all. Wait, that's not true; it did have a stuck caliper in the drivers side rear at 70k miles, but that was fixed pretty easily.
I did some mods to the truck in the first two years of ownership; 2 inch lift, custom engine and transmission tune by Klug Performance, Air Raid CAI, Anzo projectors with LED bulbs, also tinted the windows and sprayed in a bedliner. Currently has 33 inch BF Goodrich KO2's. Always changed my own oil and used the cheapest oil I could find that was Dexos rated and used AC Delco or Wix filters. It's paid off and my daily driver. I keep getting asked to sell it, and used vehicle prices are insane right now but I just can't bring myself to trade her in even though having a V8 would probably be nice. It runs like a champ and has never let me down.
