Bought my Tahoe w/175k in 2008. Yes, 175k. Had all the service records, so felt it was treated right. Has been fairly reliable in the last 25k. Oil pump went out, battery died on a hot summer day, 4x4 electrical selector switch went out ($20 @rockauto - 10 min fix). Now, I can hear the air ride constantly running, so i'm sure the shocks are leaking, but overall, I'm still happy w/this truck. Has TONS of room, 5.3 has nice power, and I'm getting about 16MPG city. Not bad for al you get. Ride is very nice and comfy. Great for road trips. Winter driving is awesome. LT has leather package, and is nicely put together.
