I have a RidePro system on my 39 DeLuxe....in my opinion it is great. The ride is very good, especially over stuff like expansion joints on the freeway. It is handy to have the ability to lower the car when parked and to raise the car for steep driveway entrances. The compressor noise is minimal (it is in the trunk and insulated from the cabin). So far, I have had to recalibrate only once....you might do a search for any problems with the setup....some people say they are having problems with the new generation of controller....but mine is doing fine.
