## What the report says

North American Vehicle Transaction Signal

- Signal: Cautiously bearish. Confidence: Medium.

Group 1 sold fewer cars than the market on both sides of the business. In our data its new-vehicle sales fell 8.3% from a year ago, against a 3.0% fall for the whole new market, and its used sales fell 17.2%, against 3.5%.

Our count has run below Group 1's own reported change in both earlier quarters this year, so these declines are more likely too steep than too shallow. The used shortfall against the market is still more than twice the largest gap we have measured.

Used cars came off their first asking price by more than a year ago while franchise dealers overall discounted less, and active inventory of used cars grew 15.7% from June, after setting aside cars listed more than 180 days at the same store as service loaners.

The new-car gap to the market narrowed every month: by September new sales were level with a year ago.

Gross profit per car, financing, service, overhead savings and the United Kingdom are outside our data and can move the company's quarter a full tier either way.

## What this report covers

MarketCheck data on retail new and used vehicle sales and inventory at Group 1 Automotive's dealerships in the United States. What we cannot see: Finance & Insurance (F&I) income, parts, service and collision work (aftersales), the United Kingdom business, wholesale and auction sales, overhead and the cost program, and gross profit per vehicle. Treat this report as one tile in the investment mosaic: a read on the U.S. car-selling side of the business, not on the whole company.
