With migration to online ordering it seems to me that dealers must adapt and change.
- Sell at MSRP, volume sales
- Provide much better support: and information during production and shipment.
- Carry less new car inventory
- Stop pushing the sale of inventory to the exclusion of online ordering.
While I agree with your four bullets as general outcomes, your list doesn't address the element of why those 4 things are issues to begin with.
The independent dealership model is the problem. Penske, Hendrick, and Ashbury make billions of dollars revenue and are all cash flow positive acting as the middlemen of the entire network. If you're GM and Ford, you'd love to capture all that portion of the distribution network and resulting cash flow. And that's why the state governments won't allow the manufacturers to get rid of the dealer model. You won't see positive progress to your 4 bullet points without removing the state by state franchise dealer laws that protect the old business model.
MSRP would simply be "the price" if the manufacturers were actually setting prices. But all the independent contracts that GM has with its dealer network prohibit GM from setting prices. And since GM isn't the one actually selling, each independent network gets to establish its business planning (sales, support, and service etc). Floorplanning dealer stock is crucial for the health of a supply chain where the seller and manufacturer are different entities. But if you want to see improvements as an end customer, you'd have to break the whole thing and allow business to consumer sales.
