Car Wash Advisory tracks the investment banks and M&A advisors involved in qualifying car wash transactions of five or more sites. These annual league tables provide a side-by-side comparison of advisor activity in mid-to-large car wash M&A, ranking firms by both the number of qualifying transactions advised and the total number of car wash locations represented.
Deal count provides insight into how frequently an advisor participates in qualifying 5+ site transactions, while site count helps show the overall scale of the car wash businesses involved. Together, these rankings offer a clearer view of the firms advising owners, operators, and investors across the larger end of the car wash M&A market.

Car wash M&A activity can be measured by both transaction count and site count. Deal count shows how often an advisor participates in qualifying transactions, while site count reflects the overall scale of the businesses represented. For that reason, Car Wash Advisory ranks advisors using both measurements.
Represents the total number of car wash locations included across those qualifying transactions.
Represents the number of qualifying car wash transactions associated with an advisor during the calendar year.

The 2025 results demonstrate why both measurements are important.
While Car Wash Advisory was among the most active advisors by qualifying transaction count, the site-count rankings provide additional context around the scale of advisor activity. Car Wash Advisory ranked fourth by total sites represented, with 41 sites across its qualifying transactions.
The difference between these two rankings shows that transaction count alone does not always communicate the full scale of an advisor’s activity. Evaluating both deal count and site count gives owners a more complete view of advisor experience, transaction volume, and market involvement.
Car Wash Advisory first appears in the provided league table data in 2022, when the firm ranked second by deal count and third by site count with 21 locations represented.
The firm continued to rank among the leading car wash M&A advisors in the following years:
These rankings reflect Car Wash Advisory’s continued involvement in multi-site car wash transactions across different market conditions and transaction environments.
The league tables are compiled using publicly available information about mid-to-large car wash transactions and the financial advisors associated with them.
Transaction details are not always publicly disclosed. Some private transactions may not identify the advisor, number of locations or complete transaction structure. As a result, these rankings represent the best information available at the time of publication and may be updated when additional details become available.
The rankings are based on deal count and site count. They are not rankings of transaction value, valuation multiples, client satisfaction or the overall quality of an advisor’s services.

A car wash M&A league table ranks investment banks, financial advisors and other transaction advisors based on their involvement in car wash mergers, acquisitions and strategic investments.
These rankings make it easier to compare advisor activity across the industry and understand which firms are participating in significant multi-site transactions.
The advisors are ranked using two measurements: annual deal count and annual site count.
Deal count measures the number of qualifying transactions associated with each advisor. Site count measures the combined number of car wash locations represented across those transactions.
Deal count shows how many transactions an advisor worked on during a particular year. Site count shows how many car wash locations were included across those transactions.
An advisor may rank highly by deal count after completing several transactions involving smaller portfolios. Another advisor may complete fewer transactions but rank higher by site count because those transactions involved larger car wash platforms.
Car wash transactions vary significantly in size. One transaction may involve a single regional platform with dozens of locations, while another may involve a much smaller group.
An advisor involved in one large portfolio transaction could therefore represent more locations than an advisor involved in several smaller deals.
For purposes of these league tables, mid-to-large transactions generally involve multi-site car wash businesses rather than individual single-site sales.
Because transaction structures and publicly disclosed information vary, inclusion is based on the available information for each transaction and Car Wash Advisory’s league table methodology.
No. The rankings are based solely on the number of qualifying transactions and the number of car wash locations represented.
Transaction values are frequently kept private, which makes it difficult to create a complete and consistent ranking based on dollar value.
Not necessarily. Many privately completed transactions do not publicly disclose the advisor, purchase price, site count or other important information.
The league tables include transactions that can be reasonably verified using publicly available announcements, company information and other industry sources.
Transactions may involve more than one financial advisor, particularly when separate firms represent the buyer, seller or different parties to the transaction.
When multiple advisors are publicly identified, the transaction should be recorded according to the league table’s established methodology. Joint advisory assignments should be treated consistently across all years.
The tables may be updated as new transactions are announced or additional information becomes available about previously reported deals.
Historical rankings may also change when an advisor, operator or other party provides verified information that was not publicly available when the table was first published.
Yes. Advisors, car wash operators and other industry participants can contact Car Wash Advisory to submit a qualifying transaction, correct an advisor attribution or provide updated site-count information.Submissions should include a public announcement or another reliable source that can be used to verify the transaction.Transactions may involve more than one financial advisor, particularly when separate firms represent the buyer, seller or different parties to the transaction.
When multiple advisors are publicly identified, the transaction should be recorded according to the league table’s established methodology. Joint advisory assignments should be treated consistently across all years.
