A WashIndex operator profile assembled from 10,335 AI-extracted Google reviews across 23 locations in 1 states. Customer-experience signals, damage rate, membership health, trade-area competitor density, and a full per-location breakdown.
23 locations across 1 states · dot size scales with review volume
Carnation Auto Spa operates 23 locations across 1 state, all in Texas. It operates primarily on the Detail Shop format and carries a weighted-average Google rating of 4.55★ across 23,307 customer reviews.
Staff (+0.84) and facility cleanliness (+0.83) score most positively. The chain's standout weakness is equipment uptime at -0.46 — customers repeatedly cite broken vacuums, dryers, and tunnel equipment.
Membership cancellation friction is non-trivial at 19.0% of membership-mentioning reviews; reviewer-reported vehicle damage is at 1.20% of reviews.
Chain-level monthly rating has stayed within ±0.3★ of its baseline across the full data window, with no sustained anomalies in either direction.
Review velocity & rating, month by month.
Review activity at Carnation Auto Spa locations spans 28 months — from January 2024 through April 2026 — with 13,240 customer reviews captured across the chain in that window. That averages out to roughly 473 reviews per month, with peak monthly velocity hitting 889 in October 2024. Comparing the most recent 14 months to the earlier 14, review velocity is trending down: an average of 445/month recently versus 501/month earlier (-11%).
Monthly rating has been remarkably stable: a mean of 4.61★ with a standard deviation of just 0.11★. The chain's best month (May 2025 at 4.81★) and worst month (February 2025 at 4.33★) sit only 0.48★ apart — an operationally consistent chain across the full data window.

Operational health signals
Average competitors near each location.
The average Carnation Auto Spa location operates in a market with 6.1 other car-wash businesses within a 1-mile radius — high trade-area density by the standards of the broader US industry. Expanding the ring outward, density grows to 49.4 competitors within the 1–3 mile band and 83.4 within the 3–5 mile band, for a total of roughly 139 nearby car-wash operators inside the 5-mile trade-area boundary on average.
The distribution across locations is uneven. 0 sites (0%) have no other car wash within 1 mile, 2 (9%) have 1–2 competitors at that range, 8 (35%) have 3–5, and 13 (57%) operate in densely-competitive urban-core markets with 6 or more car washes inside a 1-mile ring. Median competitor counts (a less-skewed view than averages): 6 within 1 mile, 35 within 3 miles, 67 within 5 miles.
Quality of nearby competition matters as much as raw count. The average Google rating of competitors within 1 mile of a Carnation Auto Spa location is 4.45★ — that's the bar each site is benchmarked against by customers choosing where to wash. Per our Car Wash Cannibalization Research, trade areas with 3–10 same-quality competitors typically produce the strongest customer-ramp economics for new operators; empty markets and saturated markets both underperform.
Most-competitive sites in the network: Fort Worth, TX (15 competitors within 1 mi, rating 4.5★); Bedford, TX (12 competitors within 1 mi, rating 4.5★); McKinney, TX (12 competitors within 1 mi, rating 4.4★). Least-competitive sites: Mansfield, TX (1 within 1 mi, rating 4.5★); Carrollton, TX (1 within 1 mi, rating 4.6★); Lewisville, TX (3 within 1 mi, rating 4.6★).
Other car wash places within ring distances of each Carnation Auto Spa location, computed by haversine distance against the WashIndex location index. Sister sites in the same chain are excluded.
What customers call out by name.
Free vacuums are the most-mentioned amenity at Carnation Auto Spa locations, surfacing in 1.9% of customer reviews. For chains where free vacuums lead, that's typically the strongest single retention amenity — express-tunnel customers explicitly value the post-wash vacuum bay and chains that remove or paywall the vacuums tend to see a measurable rating drop.
Beyond the top mention, the next tier of customer-noted features includes hand-dry service (1.4%), tire shine (0.7%). These represent the chain's "talked-about" service mix — features customers either appreciate enough to mention or complain about when they're missing.
States served.
All 23 Carnation Auto Spa locations operate within Texas. The chain has not yet expanded across state lines, which means underwriting and operational benchmarks are concentrated on a single state-level regulatory and labor environment.
| State | Locations | Total Reviews | Avg Rating |
|---|---|---|---|
| Texas | 23 | 23,307 | 4.55 |
Every site, scored.
Across the 23 Carnation Auto Spa locations with scored review data, the median Google rating is 4.6★ and the chain-wide mean is 4.57★. Standard deviation across locations is 0.09★ — a measure of how consistently the chain operates from site to site. A standard deviation below 0.2 indicates highly consistent operations; above 0.4 indicates the chain has meaningful per-location quality variance, often tied to acquired versus organically-built sites.
Distribution by rating band: 0 locations below 3.5★ (0%), 0 between 3.5–4.0★ (0%), 0 between 4.0–4.4★ (0%), and 23 at 4.4★ or higher (100%). The most-resilient car-wash operators in our research typically have at least 60% of locations in the 4.0–4.4★ band — that's the rating tier with the lowest cannibalization risk when new competitors arrive.
Highest-rated location in the network: Southlake, TX at 4.8★ (547 reviews). Lowest-rated: McKinney, TX at 4.4★ — a 0.4★ spread between the chain's best and worst-performing sites. The busiest location by review volume is Dallas, TX with 3,301 reviews, reflecting both market size and customer-traffic density.

About this profile
Every operating-quality signal on this page is derived from 10,335 customer reviews of Carnation Auto Spa locations, processed through WashIndex’s 55-field LLM extraction pipeline. Competitor counts within 1 / 3 / 5 mi rings are computed by haversine distance against the WashIndex location index across the chain’s states and immediately adjacent ones (sister sites in the same chain are excluded). Monthly review and rating trends are pulled from the raw Google Maps review feed. 4 spam-flagged reviews were excluded from the aggregates.
See our full methodology for the extraction pipeline, validation samples, and aggregation logic.
