Seems like OEM's are trying to work around their needs (and Dealers) instead of the online shoppers.
Here's a fun project, pretend you're in the market, shop your top 3 selling new models against the top competitive brand models in your market area for both lease and buy payments with $0 OOP and with $1,000 total. Do it like a customer would have to online, use any websites (OEM, 3rd party, dealer), and communicate with dealerships if you have too, in any way offered: chat/text, phone, email, or form. Build a history, rank the total value, and study it.
It won't take long to see where the big gaps are in either your own store or your competition's online vehicle shopping process comparatively. Just gathering information online to make next step decisions in the buying process is not that easy across the board, and if you make contact with dealerships with questions to get answers, it's like the wild west. Mass confusion is the norm it seems like, getting specific details is not easy.
After you do this, think about why generally 70% of customers which purchase remain anonymous until they visit your showroom.
Are any of the online shopping process tools doing any thing substantial to build trust with shoppers during this process?
Now pretend shop and order a Tesla:
