IN STOCK ALL THE TIME! Forget the factory installed unit-this doesn't SLIDE! I still think this is the best! Sits right where you need it, it has a nice, deep well for storage, it flips up out of the way if you need to do so and the quality is really good. Does not interfere with the rear cup holder or anything in it too! Still the best for such a nice storage and 'rest! For the R53, R55 or R56-specify which when ordering, please... For the record, ours (shown) is finished in leather to match our Montecarlo interior. The unit is finshed in black leather.
