Today, my car decided to start vibrating quite noticeably. After approximately 25-30 mph, the whole car seems to shimmy and bounce. I can feel it even in my legs, and my purse in the seat is bouncing all over the place. This is a sudden problem. I could not get it to go away, but was only able to test up to about 62 mph due to slick roads. It almost feels as though if it were a manual, it wasn't being downshifted fast enough or shifted up too early. Not sure on proper idle rpms, but right now it is idling at 500 rpms, and at 2000 rpms at 62. Also, b/c of icy roads this morning, I spun my way up a hill pretty much. Not sure if it is pertinent, but figured I would throw that in there. BTW 20,500 miles

I wonder if you have a bent or damaged wheel rim or damaged tire? You better take precaution and get this checked out. If your car's suspension contacted anything on spinning out it may have knocked the steering out of allignment but at least get a friend that is knowledgeable with cars to drive the car and determine if the car is safe to drive to a "tire/wheel alignment shop".
If its not your wheels then open the hood when the car is running and see if anything on the left side of the engine is wobbling.
