I’m with you Mac. I’m guessing there is not the research done when the owner of a dealership buys an IBA compared to a commercial wash owner. The dealership does not have to rely on it to generate any income, be competitive with any other washes and probably does not have to worry about taxing the throughput either. Also - there will probably be and employee around 100% of the time it is used to prep/re-clean or touch up anything missed.
They also don’t have to provide a wash quality finish worth $15 or $16.
The companies that make these machines have not had to advance technologies because they don’t have to keep up with the advancements in the commercial systems and it costs money to do that. Dealership owners are not car wash owners and probably don’t have the expectations from their equipment and are probably also not aware what can be done by a quality machine. And if they are, they know it comes at a bigger price
Distributors of these machines will probably tout their simplicity, ease of maintenance and low cost to operate and purchase, knowing they don’t have to approach tunnel quality finishes like the top machines are capable of doing.
These machines exist because there still is the supply and demand.
