Thinking about replacing my 2005 4WD SLT Plus (172K miles) with a 2012 Yukon 4WD XL SLT2 (all the bells and whistles) with 62.5K. My 2006 is mechanically sound but has some roof and hood fading. The 2012 is selling for $ 20.5K and has a small dash crack and broken front passenger door armrest/pull. It also has a few minor scratches and one small door ding. I could probably get it for $20K before TTL. My only concern is that the 2007-2014 seem so sluggish compared to my 2005. They also seem to be less nimble and have a larger steering radius. On the other hand, OEM parts are beginning to dry up for the 2002-2006 models. Any opinions as to what I should do (get the 2012 or pass).
Should I?

That's too much money for a 2012 SLT, IMHO. I paid $20K for my 2012 XL Denali 3 years ago with 92K on the clock. Low mileage doesn't mean as much to me as how it's been driven. Given that it has a broken armrest/pull, I'd say it probably made a billion small trips, driven by an owner who didn't treat it gently. And, if you're already feeling like the 5.3 in this generation is sluggish, do yourself a favor and get a Denali with the 6.2. That engine is a BEAST. I liked my first one so much I bought a second one.

GM was pretty heavy-handed with the torque management on GMT900. A Blackbear tune seriously woke up my 2008 2500.
I'll continue to scream it from the rooftops - AFM, for me, is a deal breaker. But if you get the 2012, you can kill two birds with one stone by getting a tune to 1) disable AFM, and 2) reduce torque management and increase responsiveness. Also, the six-speed is a nice improvement over the 4.
And as said above, if you test drive one with a 6.2, you'll never "settle" for a 5.3.
Price does seem a bit high, but those are pretty low miles for an 8 year-old truck.

Thanks for the advice. The dealer has dropped the price by a bit over $1K. Price seems in line with what I see on-line and I can't find any good private party ones within 200 miles of El Paso. Most on the small lots have rebuilt titles. I'm having wet feet so will keep looking. BTW, what mileage are you getting in the Denali?

AFM is Active Fuel Management. Some refer to it as DOD or Displacement On Demand.
It is where the vehicle will disable 4 cylinders through the use of collapsible lifters that allow the cam to keep turning but not open the valves. It also shuts off fuel and spark to those cylinders. This is done with split second timing of applying and removing oil pressure to the collapsible lifters as the motor is running. If for any reason the pressure isn't where it needs to be in time, due to plugged oil lines or slow pressure valves, the lifter takes a beating and eventually fails.
This feature is able to be turned off through the use of devices like Rangers AFM Disabler or through a tune. Others go so far as to physically replace the AFM parts with NON-AFM or AFM Delete parts. This also requires a tune.
If it's just me in the car and I'm driving like a normal person, 18-19 is the norm on the highway, though I've gotten 21-22 on a few trips. If I'm hauling the my wife and kids, and a whole heap of stuff, or driving like a hoon, I'll get 17. Hauling our 4000 pound trailer with kids and gear, I'll get 11.

What Wade said. And, the 6.2L didn't get AFM until 2010. If your 2006 is well-maintained and treating you right, I'd get the thing painted and drive it another 10 years if it were my money.
It'll go 300K easy.

Used prices on the GMT 900's has jumped (actually all vehicles).
Consider throwing 2k into paint etc on the 2006....

BTW exactly what OEM parts have you found that are drying up for the 00-06? I haven’t had a problem except for cosmetic pieces or parts that can be sourced from wrecking yards or eBay.
