Josh,
Just wait until you live with the car for a little bit. At first, it's going to sound really loud, because you aren't used to it and it is a novelty. But once you live with it and learn how to drive it well, I think you'll be fine. I've never heard one that is SO loud, it couldn't be idled down the block without really pissing off the neighbors. It's a matter of how much you like them...
