Sound is what it is for me. Now I haven't listened to any of the more expensive electric cars, but from what I've heard so far, Tesla sounds the best. Some of these other ones sound absolutely terrible and I hate it whenever I hear one. That's one thing I'm happy with Tesla. So far, their cars seem pretty quiet without that annoying ring to them. (Now as far as how loud, that's not what I'm getting at. I can listen to a loud diesel or a modified muffler all day, but with these electric cars, it's their annoying ring is worst than fluorescent lights.)
