What stands out

Five things to take from this

  • Suburban Collection is the default answer, named in 190 of 500 answers (38%). LaFontaine Automotive Group follows at 149.
  • Glassman Automotive Group is a memory answer. Claude named it in 98 of 100 answers, the four web assistants in 14 of 400. The model knows the name; the live web sends buyers elsewhere.
  • Suburban Collection leads 5 of 8 topics. Best of Michigan Auto Sales leads Used cars; CarMax leads Trade in; LaFontaine Automotive Group leads Trust and experience.
  • Cars.com, a marketplace, was named in 60 answers. Ranked against the sellers it would sit 15th. Every one of those answers is a shortlist a local seller could have been on.
  • Driveway sold 6,616 vehicles in the window and was named 2 times. Bowman Chevrolet sold 862 and was named 59 times. Volume and visibility are not the same market.

Driveway is the online storefront of the national group that owns Suburban Collection, so its units include Suburban inventory sold through that channel rather than a separate local rooftop.

Group named is the count for the dealer group a rooftop belongs to, where the assistants name the group rather than the store. Sales are inferred: a vehicle that left the selling website and met the sold detection rules, counted per website, all makes, new and used together. Volume and visibility are measured on different things, so a mismatch is a finding, not an error.

Method

How this was measured

  • 50 questions across 8 topics, written the way a buyer in Detroit would type them. None of them names a seller.
  • Every question was put to Claude, ChatGPT, Copilot, Gemini, Google AI Overviews from a connection in United States, in two runs, 500 answers in all.
  • A judge model read each answer and listed every business it named, whether the answer linked to that business, where it first appeared and how it was described. Names are merged on a normalised form and known websites are attached where the answer linked to them.
  • Marketplaces, finance providers, manufacturers, service chains and reference sites are classified and kept out of the seller leaderboard. They are reported separately where they matter.
  • Each question was asked once per assistant per run. A single cell can turn on chance; the pattern across the study is the finding.
  • This measures being named, not being visited or chosen. Appearing in an answer is the first condition of being considered.
  • Sales figures are inferred from vehicles leaving dealer websites and are asking prices, not transaction prices. They cover all makes.
