What kinds of car washes does Billings have?
The Billings MSA contains a wide mix of car wash formats — from express tunnels and full-service operations to detail shops and self-serve bays. The bar chart below shows how many locations of each format have been formally classified by our LLM-based format classifier (which reads each operator's own website to determine the format), with the avg Google rating per format displayed alongside the count.
The format with the highest customer rating is Detail Shop at 4.88★ across 8 locations — typical of the format, which is staffed, hand-finished, and oriented toward customers who care more about wash result than throughput. The lowest-rated format is Self-Serve Bay at 3.70★ across 2 locations. Format-level rating gaps of this size are common — different formats serve different customer occasions and have inherently different expectations.
Of the 108 total locations in the MSA, 83 (76.9%) are currently unclassified — these are typically smaller independent operators without enough website signal to determine format unambiguously. Their inclusion in the overall location count is correct, but format-level statistics below should be read as describing the classified subset only.

|---|---|---|---|---|---|---|
| Unclassified | 83 | 76.9% | 2,629 | 4.13 | 2.51% | 28.6% |

What is the household income near Billings car washes?
Each ZIP in the Billings MSA has been joined to IRS Statistics-of-Income data (tax year 2022, mean Adjusted Gross Income per return as the income proxy) and to the per-location Google rating dataset. The scatter below plots every car wash with at least 10 reviews against its ZIP-level income, with each dot colored by format and sized by review volume.
Across 49 qualifying locations the simple Pearson correlation between ZIP income and Google rating is -0.26 — a mild negative correlation. Higher-income ZIPs in this MSA host slightly lower-rated car washes on average, which is unusual and worth investigating at the operator level. The mean-of-scatter location sits at $77K AGI/return and 4.17★.
Car wash count and quality by income tier
Grouping ZIPs by income tier shows how location count and average rating shift across the income distribution. The blue bars are location count per tier; the orange tick marks show the average Google rating across all car wash locations in that tier (scaled against the same y-axis).

Who operates the most Billings car washes?
The Billings MSA hosts 11 different chains alongside 91 independent operators (single-location or unaffiliated sites).

About this analysis
Car wash inventory for the Billings, MT CBSA is determined by point-in-polygon test against the official US Census county boundaries (TIGER/Line, 2024) for the 3 counties that make up the MSA. Each location was verified to fall inside one of those county polygons; lat/lng comes from Google Maps metadata.
Operating-quality signals are derived from 1,622 customer reviews processed through WashIndex's 55-field LLM extraction pipeline. Format classification comes from a separate per-location website-reading classifier. ZIP-level income data is from the IRS Statistics of Income (tax year 2022) — mean Adjusted Gross Income per tax return, which is directionally aligned with ACS median household income but available without authentication.
