Purchased used in 05 $4500 never regretted having a Buick. Best mileage 38 average 27 on long trips. We like the 8 way seats and all the gadgets that came with the car. We have another Park Ave a 92 and what a nice car this is our fifth Buick all Park Avenues. Today it has 155,000 miles and we expect another 100,000 plus miles.
8 way heated seats and smooth ride. Extra large trunk.
To be able to obtain all parts from an auto parts dealer. Not from Buick such as the rear air shocks.
