Current owner of a 2018 GC Summit, 4x4, V8
Ive had a ton of GC. 2007 Laredo, 2011 Laredo, 2014 Limited, 2015 Overland, 2018 Summit. Needless to say you can call me a fanboy, enthusiast, whatever.
The Jeep GC is an excellent vehicle in terms of cost/features. You will be hard pressed to find an equal match of what you get in a Summit compared to any other luxury SUV. Jeep has its flaws though. The service department is going to vary greatly depending on dealership and the reliability is hit or miss. Seriously your jeep is either going to be trouble free forever or youll have to keep going back to get little stupid things fixed. When I brought home my brand new 2018 summit the front headlight didnt work. Took them 3 days to figure out the problem and fix it.
I cross shopped the tahoe and the gc extensively. If im being honest, I still am. Might ditch the jeep for the tahoe only because Ive had so damn many of them.
The Jeep is certainly easier to drive and much easier to park. It has a ton of safety features and new tech that the tahoe may or may not have. It really all comes down to size and price. Do you do a ton of highway driving? If so, you might lean towards the tahoe since it is a steady cruiser and a dream for long trips. If you find your day to day to be more city driving, parking garages, and rush hour traffic, then you might consider the GC for its handling and smaller footprint.
I have no kids, no wife, I dont tow anything. I only want the tahoe for its road presence and general badassness. Is that a legitimate reason to buy the vehicle? You bet your ass it is. I dont need to justify a damn thing. But thats me. If thats not a good enough reason for you than the GC with the V8 will be more than enough to satisfy your needs.
