My snakebit, elderly BMW tried to commit suicide again. It has since been patched together at no small expense, but my husband wants to send it off to the automobile rainbow bridge. I looked at the various overpriced and tedious options, before deciding that the best replacement for my little ragtop was -- obviously -- a Mazda Miata. If you had an arthritic left knee and arthritic ankles and feet, would you be sensible and buy an automatic or would you choose something that was more fun? Or should I just buy some old lady, square sedan?
