I'm in the market for a new S2K and just test drove one that's been garage kept.

It feels like one of the rear wheels is driving over bumps (obviously when there aren't any). There's nothing visibly wrong with the tire or wheel.

How concerned should I be? I'm hoping this isn't indicative of an issue with the differential or something in the suspension. What would be the best way to find the issue? The car only has 36k miles on it...

At what speed? If at freeway speed, i would say maybe unbalanced tire? But i personally wouldn't buy it if you suspect a differential problem...

Strange bumping sensation from your rear = horny donkey

If the rhythmic bumping remains after driving for four or five miles you may have a tread separation. It's very hard to see even with the tire off the car, sometimes you can feel it by running your had around the tread, often you'll have to spin the tire slowly to see that it's out of round.
