Well, I say the mileage all depends on your comfort level, what you think is a lot of miles.., and your wallet of course. I saw an ad for an H2 last week, it said "only 72,000 miles"..., I get nervous when my vehicle approaches 15,000 miles...
I have been in '03 and '04 H2's with about 25k miles and they were both rattle traps. The newer ones, 05 and up I found aren't as bad, I htink the Lux package might have to do something with that too, it has some kind of interior upgrade... Now of course it all depends on your own rattle level too, I've been in cars that are ready to fall apart and the owners have no clue, just drive around whistling like nothings going on and I am shaking and sweating profusely....
I have read on here that the used prices at some Hummer dealers have gone up overnight since the scare of the H2 demise. My guess would be the prices will not go down if and when they really shut down. I would think they would level off and maybe even go up in some cases. I mean you will still find a ton of used high milage 03's around but where are you gonna replace a 1-3k mile 09 when they aint makin them any more... I think those people will hold all the bargaining power... heck it's even tough to find a brand new 09 now at a dealer...
As to whether or not the 49k mile, $23,800 you are looking at is a good deal or not, you didn't sepcify what year it is. If an 03 probably not, an 09 I would say ok
