We categorize vehicles into one of three sizes; Small, Medium, and Large. The most common question we get about vehicle sizing is "Is my vehicle considered a small SUV?" From our brochure :

"Generally speaking if a 6' tall man needs the assistance of a stool or step ladder to wash or polish the roof than the SUV is NOT considered small. This is not an absolute rule and we reserve the right to make SUV size determinations. Vehicles with 3 rows of seating with almost always be considered a "Large".
