Most conversations about opening a wash start with the machine. The better starting point is the ground it will stand on, because a site that fights the wash will beat any machine placed on it.
Traffic has a shape
Vehicles need to enter, queue, wash and leave without crossing each other. A site can have excellent road visibility and still fail here: an entrance that backs onto a junction, a queue that blocks the exit, or a turn too tight for anything larger than a hatchback. Walk the path a driver would take before admiring the corner plot.
Footprint decides the category
A tunnel needs the length of its full line plus queue and exit space, which is why it suits larger plots. A rollover washes a stationary vehicle under one gantry and fits where a tunnel never will. This single constraint often makes the machine decision before any brochure does.
Services are not a detail
A wash lives on water supply, drainage and electrical capacity. Sites that were never plumbed for the volume, or that drain poorly, carry retrofit costs that dwarf small differences in machine price. The utilities survey belongs at the start of the process, not after the equipment order.
None of this argues against any particular site. It argues for reading the site first, so the machine that arrives is the one the ground can actually support.
