I can tell you from experience, I would NOT do it. I have been a GM guy my whole life. I learned a very expensive lesson, that newer is not always better. Money was not the issue but in hindsight it is all wasted money for me. I had bought a new 2007 GMC 5.3 4 speed. Best truck I owned. Sold it with 67,000 miles. It didn't take long for regret to set in. A year later I am in the new platform a 2014 Silverado CC LTZ 5.3/ 6 speed. Many issues. They had incentives, good trade value, so I double down on a 2015 Sierra CC SLT 5.3 6 speed 3.42's. Too many issues to list, but the biggest was vibrations they could not solve. I trade into a 2015 Yukon XL Denali 6.2 8 speed. Nightmare truck. Vibrations, transmission was out of the truck 2 times. 12 different warranties. Dealer offers to take it back at a reasonable trade I order a new 2017 Denali Yukon XL. After 18 months of going to the dealer with that one I gave up. I traded out into a S550. I then bought a 2013 Suburban LTZ and could not be happier. More comfortable, better seats all around a nice ride.
To be fair I will give you the good points although I feel the bad outweighs the good especially at that price point!
Fast as hell. Great gas mileage. Great presence and appearance when it pulls up. Tech is ok nothing great. Very slow booting up for the phone and bluetooth. Actually ridiculous.
The ride was too tight almost harsh. 22" rims don't help. Vibrations, and booming inside. (known huge issue, google it) Some have it some don't. Interior is the same as a pick up. Cheap inside. Nice yes but this is a 75K truck! So not nice enough. HVAC system is loud. Its just too loud, you can always hear it. Seats have to have been the worst seats I have ever owned in any vehicle. The Denali is actually worse than a pick up because it has different stitching going across the seat that feel like rubber bands across your back! No comfort at all. Very basic hard seats. Too expensive for what your getting. It wasn't the money for me, it was the lack of value.
If you go on some forums, you would not believe the issues with the new platform.
Gm is scrambling to catch up to the Dodge interior and Lincoln Navigator. They are eating GM's Lunch. Unfortunately I am a GM guy. I regret wasting my time and money on the new platform. Believe me I kept trying to convince myself it was great...it just wasn't and I went back to a 2013.
I will bet you the next platform will be much better.
You have gold, hold onto it.
