thats basically the way mine is. as i've mentioned previously it was my aunts car originally, and i never really remember it having a level or nose down attitude. but as you say if their is a load in the back it pumps right back up to the same spot.
i have been meaning to measure to get a ride height as was suggested but the weather'* been so crappy when i do go out it'* just get in the car and go!
i remember seeing another sse of the same vintage in town and drove by the house. although it'* hard to tell when its sitting in an angled driveway it does look like it sits level.
i'm still thinking of going with the "if it ain't broke don't fix it" philosophy.....at least till spring!
