Nothing. Except that's not what they do. And we're not talking millions of dollars of spare parts that will become obsolete. At the present time, FedEx has a pretty standardized fleet of tractors and trucks. A very high percentage of the tractors are Freightliners, and the basic delivery fleet is pretty much Sprinters, Nissans and the Isuzu Reach. We have some W700s and 900s too, which are a Freightliner underneath the body.
Like others have said, we will park a vehicle that has a non-operational headlight and go rent a replacement. When they made their calculations for the "savings", did they also figure-in going to retrieve the rental, taking it back, and the possible disruption to operations?
Our mechanics can't even go to the local NAPA store or order from them. It is INSANE. Off the record, almost every manager will agree with it being a stupid idea.
