Six or seven years ago, most people on this site would probably have said that such a circumstance would be a “no brainer.”
Traffic count times 0.006, count the cash. LOL
Boy, have times changed.
One thing that hasn’t changed is the fundamentals of solving the location problem; is the market economically desirable and is the location suitable as a car wash site?
For example, I have a client with a wash located next to some big box stores and there are virtually no roof-tops for almost three miles. He washes gobs of vehicles.
In one of the poorer markets north of me, there is a wash located next a super center that is doing very well. Several miles north of this site there is an exterior express that appears to be struggling.
Consequently, it is still advisable to do your homework.
What is the supply/demand balance in the market? Is the segment strong? What is the probability that motorists would stop (combined trip)? What pricing will get customers to make an extra trip? Will design, access, signage and
marketing be appropriate? Etc.
