i agree w/the enthusiast.
my dad is a chevy/gm man (tahoes & blazers).  he also owned a few mobile winshield repair franchises.  he would easily put 60k on in a year.. maybe more & a lot of that was on the streets of denver.  his SUVs would also be the family vacation car & we would drive as far as south carolina, washington state, & illinois.  the worst problem i can remember him having, was having to change a transmission in his current yukon.  other than that, he was religious w/routine maint. (he used to be a mechanic).  he always told me that if u take care of your cars they will take care of u.  i think the milage he sees out of vehicles that are not known for their longevity is proof.
if the car was taken care of & u like it.. i say get it.
