Car was Setting on the lot for over a year before i brought it. Car has 3000 miles on it.
Low speed shimmy on a new car is almost always related to inadequate tire pressures. Bump the fronts to 36 PSI cold and rears to 36 PSI cold and see if that solves the problem. Most of these cars are sold with too little pressure in the tires and that will cause it to shimmy or vibrate. If the tire pressure does not solve the problem then you need to look at balancing issues. Start with tire pressures.
