You a mechanic? What would your opinion on them be? Versus something like a Tahoe.
Yes, I am a master tech, but I mostly work on cars that come from auction, and they are treated like garbage. These cars can last a long time if properly treated, and they can last a very short time if heavily abused (like most cars that come from auction). Where as something like a Toyota will last a long time regardless. Overall these are pretty decent cars, and there really isn't much difference (mechanically speaking) between one of them and the Tahoe. It really comes down to personal taste. I'm not really a fan of real big, but that is probably my personal opinion. If you get one with 60k-90K, you should really be fine. The only things that really fail are the things I mentioned. The solenoid runs like ~200 installed, same for the thermostat. Fan is a bit pricier I believe those are usually billed around ~500 installed. The bearing for the front transfer is a bit pricier but still under ~1000, you will typically hear one going bad if you put it in 4wd and drive it. We don't have emissions testing in the part of the country that I am in, but the most common codes thrown are p0016/17 which are for the solenoid or for simple oil change (usually.)
My biggest advice would be to save ~$2000 or so for repairs that you may also end up not needing.
A couple of other things that go bad on these that is worth mentioning - The oil pressure sending unit, and the gauge cluster. I mention these specifically because the book time (What you will be charged at a shop) on the oil sending unit is at least 3 hours because it requires pulling the intake manifold. You can, however, actually replace it without pulling the intake with basic tools. The gauge cluster goes bad on 2003-2006 ALL chevrolet/gm. They used shit stepper motors for them. At the dealer, the only "fix" is to install a new gauge assembly AND have it programmed for your car. In reality you can order stepper motors to rebuild your cluster for about 6x $5 and solder them in yourself, or even just send your cluster out to a rebuild service that will do it for about $90.
The only really "expensive" repair you would ever need to worry about is as someone mentioned, the transmission. I personally have not seen very many of them go bad, but it is an issue.
