I haven't seen a scientific study to prove or disprove my thesis, so what I am about to discuss is MY OPINION only.
Observation: By the time the car shopper gets to the dealers home page, they've been on a long shopping journey. The shopper has narrowed their consideration set (# of vehicles on their favorites list) and they're looking for a dealer that will give them a productive shopping experience.
Thesis: The CTA clutter on the home page causes the shopper to lose focus.
If I am correct: An A/B test should reveal superior engagement stats seen in analytics (e.g. TIme on site, time on SRPs, # SRPs seen, time on VDPs, # VDPs seen, % Return, and even the lead gen rate, etc.).
DESKTOP:

In this example, I see13 clickable messages may or may not align with the users intent.
MOBILE:

SCENARIO: If our shopper is at a competitors store, he's taken a test drive of a Chevy Traverse, but, his wife hates the color, he pulls out his phone and he has 3 minutes to shop while the salesman is away... Eeek! he mutters, how do I find the selection of Traverses?
