Yeah, it doesn't have a lot of desire to stay on center. The steering is tight, but I wouldn't go so far as to say twitchy.

The steering wheel was replaced because during some body work (I stupidly backed into something at about 5 mph, so that's almost certainly not the cause of the alignment problem) the body shop somehow managed to gash the leather on the steering wheel, so they replaced it. I seriously doubt that they did any more than was necessary to replace the actual wheel I hang onto while driving.

I'm going to take it to the shop anyway (I don't trust myself with this sort of stuff), so I'll just ask him to think about it as he fixes the problem.
