My wife, and I wore out 2 70s Bonnevilles, and a Catalina, I rented a Bonneville last week, it doesn't rate the name Bonneville, I wouldn't buy one.
I agree, I loved the Bonnevilles a few years back. My inlaws recently bought one, and I could not believe how much less of a car it seemed. Much closer to a Grand Am than my memories of the Bonny.
