[MetroMPG]

I was also pleasantly surprised by the seats in the Metros. Not bad at all. Though I did take mine out and added some extra padding under the front part of the cushion (between the foam & springs) to get a bit more of that "bucket" shape for more thigh support.

The tire: could be a belt that's going. If it's got 4 new tires, I'd put that noisy one on the back and see if the sound goes away.
