Faults:

I have a 2005 Sebring Coupe with 37,000 miles... I've taken it back to the dealership 2 times (different dealerships). The front end shakes, when I reach 60mph. I can feel the steering wheel shake, at that speed. I was told at both dealership, nothing was wrong with my car.. each time the car was taken out for a test drive, nothing happened.

Can anyone give me some advice on what to do next?

General Comments:

I love my car.. being a single female, having my car in quality condition is very important to me. Aside from the above issue, my car has been very dependable.
