Our VP here at work moved up from the U.S a couple years ago, he bought a base Tahoe out of a rental fleet. It's been trouble free, and it's black so you don't notice the black base model door handles, he's also put a tasteful set of 22"s on it and on Friday a bunch of us helped him install a Magnaflow cat-back. It's a nice truck and you've never know it was once a rental.
I also think it's sorta cool that someone in his position drives a 6 year old ex-rental Tahoe....
