Yes, you are probably right. Seems way to easy to just be wiper motors, and they have to be just stacking up. I am also sure, as they are getting the parts/chips in, they are not going back to the older ones in the lot and putting them in those first. If we are at the back of the lot, who knows how long they may sit there. Seems like you may be towards the back of the lot if you have been waiting that long. Hopefully you have a dealership that's more cooperative then mine with helping you.
