I am planning on buying 07 or newer anywhere from 40k-80k miles, I am particular. Will only buy from a private seller, 1 owner, clean carfax. I would love to have a brand new one but I had sticker shock when we looked at some haha. They are beautiful and have room for a growing family which is def what I need. I def want to make sure someone took care of it, I have babied all my vehicles bc I pay for it monthly do I should take care of it, but I guess not everyone takes pride in what they have. So overall with that amount of mileage and if I careful about who I buy it from it should run for well over 100k miles without like engine repairs etc? Thanks all who have commented.
I was thinking the same but then I saw the NBS Z71 Tahoe's compared to NNBS which were double in price with the SAME mileage as the NBS.... TO me that means as long as you can justify the double price increase/can afford it, go for the 07+. But I wouldn't limit your search when the NBS issues have been rooted out by now, they have most of the features you're looking for in a NNBS, and finding a "good" vehicle in general should have you reverting back to the very standard practice of checking owner/service and maintenance history and simply taking it for a nice spin to see how it feels. Does it accelerate quick when you hit the gas hard? are the clunky, clicky, squeezy sounds when you make turns. Each has their respective place on the list of things expected to replace at a certain mileage and others not so much.
Havent heard of many ppl who properly checked the vehicle out having issues with the tranny going out. That goes back to finding out where it came from and who owned it. Some 17 year old kid probably tore the tranny up, or some jerk off probably never changed the fluids or never let off the pedal leading to rough hard shifts... Also to echo the Don I have a buddy who bought his OBS from a friggin 18 year old kid who tore the shit out of it, and cheap mods and lifts all over the thing... but still it drove with NO problems... his only problem in 2 years with it was a blown like 44" tire.
Good luck in your search, I would personally search for a 06/05 NBS Z71 with captains in the middle and a third row. Has e-fans, hydraboost breaks (larger), some extra HP's and TQ, Navi etc...
Key: NBS: 00-06
NNBS: 07+
