What kinds of car washes does Decatur have?
The Decatur 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 4.86★ across 5 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 Express Tunnel at 4.28★ across 3 locations. Format-level rating gaps of this size are common — different formats serve different customer occasions and have inherently different expectations.
Of the 40 total locations in the MSA, 30 (75.0%) 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.
| Format | Locations | % of MSA | Reviews | Avg Rating | Damage Rate | Cancel Friction |
|---|---|---|---|---|---|---|
| Unclassified | 30 | 75.0% | 727 | 4.03 | 0.55% | 40.0% |
| Detail Shop | 5 | 12.5% | 128 | 4.86 | 0.00% | 0.0% |
| Express Tunnel | 3 | 7.5% | 1,091 | 4.28 | 5.23% | 10.0% |

What is the household income near Decatur car washes?
Each ZIP in the Decatur 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 20 qualifying locations the simple Pearson correlation between ZIP income and Google rating is -0.06 — effectively zero. Higher-income ZIPs in the MSA do not produce systematically better-rated car washes. Operating-quality signals are dominated by per-operator execution, not by neighborhood income. The mean-of-scatter location sits at $69K AGI/return and 4.10★.
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).
| Income tier (mean AGI/return) | ZIPs | Locations | Reviews | Avg Rating | Top Format |
|---|---|---|---|---|---|

| $100K – $150K | 0 | 0 | 0 | 0.00 | — |
