Driver Seat is a little worn.
Steering wheel has foamy stuff that peels on your hands.
Can no longer shut off air conditioning.
Brakes had to be replaced a few thousand miles back.
When I was younger, we had to change the transmission.
This is by far, the most reliable, useful and safe cars to drive on the market today. It has great fuel economy for a car it's size, it's bacck seats can be taken down making room for huge amounts of cargo and still fits 5 people relatively comfortably. With a V-6 engine it still manages having a very high pickup when asked for it. THIS CAR HAS NEVER HAD A TUNE-UP.
I don't think suburbans came with v6s I think they only came with 350s, 454s, and possibly 305 engines.
But stating its never had a tuneup doesn't say much about your ability to maintain a vehicle, its going to start running like crap real soon.
Believe me, if it needed a tuneup we'd give it one. We take pretty good care of it, but we don't go out of our way for it. If we didn't get another mile out of it, it was still pretty good value.
