I'm toying with the idea of getting a second car: perhaps a used Miata. One thing that worries me is how noisy they are (or are not.) Years of driving motorcycle has left me with tinnitus and hypersensitive to noise. How noisy is a Miata? On the hwy with the top down? With the top up? And how noisy is the car in general? Mike just posted about driving a thousand mile to Yellowstone, and I'm curious what kind of experience that is. I would suspect that such a small car would have a rather punishing ride, mile after mile on the superslab.
(Of course, I could answer these questions myself through a few test rides, but I thought I'd start here.)
