2003 Buick Park Avenue Ultra 4dr Sedan (3.8L 6cyl S/C 4A)
i love this car. I don't know how the regular Park Ave is but the Ultra is awesome. The supercharger is such a convienience not to add I rarely loos the random red light races. I get 28 miles to the gallon which is great. It gets the best fuel economy in its class. If you don't have one I suggest you look into it. Great car all around.
Heated seats, sunroof, air ride suspension, 12 disc changer, venti ports, and of course the 28 mpg supercharged V6
I think new and bigger brakes are in order for this 4000 lb beast. It takes a lot to stop it, and maybe bolt down the engine like in the Regal GS and Riviera
