An interstate-corridor story needs parcel-level testing. Distinguish regional vehicle movement from the drivers who can conveniently reach, use and pay for a particular wash.
Define the corridor hypothesis
For each proposed site, identify the relevant road segment, interchange relationship and actual entry. Review IDOT traffic information at the right location and vintage. A distant interstate count does not establish traffic past the pay station.
Observe whether turning, travel direction, queueing and return to the route make the stop practical. Treat through-travel and repeat local memberships as different customer hypotheses. Do not presume every passing driver wants a wash.
Compare counties through actual operations
Use records for retail visits, billed members, commercial accounts, refunds and service mix. Census data can provide area context, but it cannot turn logistics activity or population into wash sales. Ask the seller for supportable evidence of the customer base.
Compare like formats and property scope. A self-serve wash near a local route and a tunnel near an interchange may need different staffing, maintenance and capital. County labels alone are too broad to rank value.
Verify control and technical scope
Identify parcel jurisdiction, access rights, planned-use approvals and utility arrangements with the professional team. Review lease assignment or title and environmental history. Do not rely on a highway sign or operating history as proof that a planned expansion is authorized.
Get qualified condition assessment and written repair estimates. Include service-provider travel and response in the buyer's operating plan. Equipment supported in theory still needs practical local service coverage.
Require a supportable base case
Normalize owner work, rent and continuing costs. Model a lower-volume period and an immediate repair before counting future route capture. Financing and reserve needs should be tested against the actual wash, not an assumed corridor premium.
Schedule a call with Jason to discuss the two locations and your operating radius. The next step is a site-specific comparison of access, paid demand and capital, without claiming corridor listings or universal price advantages.
Your decision worksheet
Use these questions to identify the records and decisions that matter to this topic. Bring the open items to your conversation; detailed documents can follow through an agreed private process.
| Question to resolve | Evidence to bring | Why it matters |
|---|---|---|
| Which drivers can conveniently reach the wash? | Entry, turning and route observation at the parcel. | Distinguish regional traffic from realistic customer access. |
| Who repeats and who only passes through? | Retail, member and commercial collections. | Test different demand hypotheses without invented capture rates. |
| Can service support cover this location? | Qualified vendor availability and operating backup. | Make corridor distance part of the ongoing cost plan. |
| What does each county comparison include? | Site rights, format, condition and normalized earnings. | Avoid assigning a universal corridor discount or premium. |
