Can I make the cabin quieter inexpensively? Some foam spray on the wheel well, some foam pad in the firewall, some rubber coating on the chassis, etc? I know the engine is a lot noisier than new and so is the trans. Maybe I am dreaming for a new car.
Dynamat makes cut-to-fit sound mats that covers the whole floor inside the car. You'll have to remove the seats, center console (if it has one), and pull up the carpet. It's kinda alot of work, I'm thinking about installing a Dynamat in my little Accent. You maybe better off just having the car undercoated, esp if it's ever driven where there's road salt (these cars rust away fast in the north, so I hear). I always thought the Taurus was pretty quiet as-is, except for the transmission wine the ax4n is known for. Even different brands/types of tires can really change how much road noise is inside the car.
