A waste of time is when you put your prado in for a service and they say you will have to bring it back as they are going to replace the bolts but don't have any In stock( WTF)) Take it back a week later, pick it up only to be told that the hold to bar is going to need to be replaced as the holes are elongated. You guessed it no to bars in stock. Back a third time and after a brief discussion about the efficiency of the service department and the extra 2 days they had my vehicle walked away with a toyota WDH system. Does not have adjustable ball height but was happy to get something for all my time.
