Have had X3 sport, Cayenne S and currently have Cayenne Turbo.

The X3 wheelbase is too short and too bouncy. Shakes you driving on normal streets, making it exhausting to drive. That's why I traded it off. Otherwise no problems.

04 CayenneS with air suspension. Was very affordable $10K and no problems. Much smoother riding, nice.

Traded 04 CayenneS for 05 Turbo to get the cornering lights because of some vision problems. Before getting didn't think anyone needed a Turbo Cayenne. Now think it is a requirement. Same smooth ride as S and no problems once I got the previous owners "upgrades" put back to factory. They had put LED bulbs in without resistors to match the original bulbs causing the lights to flicker or not work at all. Has to replace them all and 2 receptacles they had messed up. PO also put smaller S brake pads on instead of turbo causing problems with almost all the other brake components requiring replacement. Still was under $16K to purchase and put into top shape.

That is my experience with those SUVs. Very happy with the Cayenne Turbo.
