Do yourself a favor. Find one and buy it

I bought a normally aspirated 2005 Park Avenue that had suffered years of road salt abuse and was scorched in a garage fire. Looks rough, but still handles well with plenty of power. Can easily reach it’s top governed speed if I want it to. Clean exhaust and still gets 29+ mpg highway at 70 mph. Quality seat and ample leg room to prevent stiff muscles and sore joints on long trips. My ‘96 Roadmaster is my only other car that can do that. Almost 200k miles on her, and with a little maintenance just keeps getting better to drive. Superb for long trips and carrying passengers in comfort. Dashboard display and controls far superior (clean and simple) compared to some 2023 cars I had the misery of driving recently. No touchscreens!🙂Best $800 purchase I’ve made in a long time.


I made a great Yard Sale purchase

The car only had 45,000 miles when I purchased it and it had nearly 200,000 when I traded it in to the dealer. I got nearly 32 MPG on the highway. I really enjoyed the ride and comfort with the car until the transmission started giving intermittent problems so I traded the car for a new one.


Outstanding ride

I have owned four Buick Park Avenues. The 2005 is by far the best riding model year. Everything works as designed. Very comfortable seats, lots of room. In the trunk, for an eleven day Boundary Water canoe trip, I fit personal gear for five people, group gear for ten people, and eleven days of food for ten people.
