I bought this Park Avenue from a family friend with low miles after my Honda CRV was totalled in a head on collison. It would not have been my first choice having sworn myself to Honda and Toyota. I've reconsidered after owning this Buick with good gas mileage (20-22 city/ 30+ hwy) and a luxury interior (leather power interior) looking a bit like a luxury car compared to what I've driven in past. Few repairs given the age of the vehicle. I performed regular maintenance. One comment on exterior design, when you open the windows first thing in the mornings the water will pour off into the car onto the power controls. For this reason buy vent visors or keep towels handy in the morning.
Leather interior, power interior, good gas mileage, reliable car.
I think they have fixed this but the exterior design water sitting on top of the car pours in the car when windows are opened in the morning and one drives. This pours water in on power control panel on doors.
