It is a concern especially when hearing some members here complaining about the faults and glitches. However, the question is how does the Adaptive Drive affect the driving pleasure for "normal" drivers (i.e. those who don't really push their cars to its limits)? If a sport suspension setting is not affecting the comfort level of the vehicle or the standard suspension is already giving the driver pretty good control over the day-to-day manovering of the vehicle, then one may not really need to order this expensive option. I may be wrong but it seems that this adaptive drive option woud be required or nice to have if the driver likes to do high speed manovering with this 5000 lb vehicle.
