WOW! This SUV is NICE!! First of all, this GMC Yukon XL is the Denali package. Now thats not just a fancy name plate. It completely makes this car different from its Chevy Suburban and standard GMC Yukon XL cousins. The Denali is basically the Cadillac Escalade with a GMC badge and this is why. As opposed to the 5.3L, It has the 6.2L Vortec V8 engine and 6 speed automatic transmission, same as the escalade's. We're talking 405 horsepower folks, 100 horse more than its cousins! This truck gets with the program, tons of power yet still fuel efficient. No worrying about road conditions and if you should put it in 4x4 or not, just like the legendary Escalade all wheel drive, this has it! Magnetic ride control suspension, same as the escalades, hook up to a boat or trailer, this thing actually rises in the back to level out the load! So those are the basics of the powertrain stuff, now lets talk comfort features. Dual power heated leather seats, plus heated seats in the back, memory seats, sunroof, digital 3 zone climate control, etc etc. Want easy access to the 3rd row seats, how about POWER FOLDING 2nd row seats which you can do from the drivers seat or the rear doors, plus a power lift gate that you can control from drivers seat, the key fob, or the actual door its seft. Speaking of key fob, remote start is standard and we have both sets! You really need to come in and see this rig to appreciate it and get a grasp of all of its features. Basically, if you want to best there is in a quality full size SUV, if you want comfort and luxury, capability and easy to drive, look no further!
