I got the Towncar out for a drive over the weekend for the same reason. It was nice having that doing something beyond sitting and catching dust for a change. I did find it's got some oddness in the front suspension though, I hit a pothole and the wheel tried to pull out of my hand. Not sure whats up with that, but it may be time for a front end checkout. Its due for a front brake job anyway. I bought the pads last year and never did it. They're not critical but it gives me the occasional squeal that just makes my skin crawl.
