I have been seeing more and more DeVille's (and other cars for that matter) that have a rear end that sags to the ground. It looks as though there is 200 pounds of stuff in the trunk, but there is noone in the back seat or anything. Why do these cars do this? I thought the car had an auto level control, so this would seem even more unlikely to happen. It makes the car just look old and beat, and I see it SOOOOO much in these devilles. I hope to god mine doesnt look like that when Im driving. Anyone know why this happens and how I can check to see if mine is sitting right in the back??
