I know it is a lot of money but when a car reaches a certain age I am a firm believer in taking it to the dealer and having them perform a full service for the age and mileage of the vehicle. I have driven cars away from this service feeling like they were brand new because they tightened up all the suspension and steering, adjusted the brakes, replaced out all the worn bushings, greased every possible joint and hinge and not to mention the regular plugs, wires, fluids and such. Once again it will cost you but the dealer knows what needs to be done for the miles. I cringe when I pay the bill but when I get in the car, start it up and drive off the lot I know it was worth it for the new feeling of a tight vehicle.
