I reckon its great. No regrets at all about spending the extra money for it. The sport mode IS too hard for continual street use, but in the normal compliant setting the system instantly stiffens up (and it IS instant) if you adopt a more agressive driving style. Similarly in sport mode in it softens up if rough roads are likely to upset the balance. There is absolutely no body roll and even under hard braking no front end dive. In either mode.
