In some cases, it is economically feasible to convert a lube building with pits into an in-bay automatic facility.
If the lube is a viable candidate for this process, it would have to be functionally obsolete. In other words, worn out and a lack of customers.
If the subject can no longer sustain itself as a lube, an owned-goods service that shares many characteristics with carwash, I would want to determine if the market is appropriate for carwash products. This is often considered the first step of solving location problems.
Once the potential of the market is determined, you can measure anticipated revenue, investment and operating expense. This information will show if there is enough demand in the area to support the construction and operation of the proposed facility.
I hope this helps answer your question.
