* The specific dimensions of the Sprinter van: Sprinter vans come in various lengths and heights. A longer or taller Sprinter might not fit.
* The type of car wash: Automated car washes have varying size restrictions. In-bay automated washes are generally smaller than conveyor-style washes. Touchless washes often have less stringent size limitations.
* The specific car wash's dimensions: Even car washes of the same type can have slightly different sizes.
In short: You'd need to check the specific dimensions of the Big Blue Bus Sprinter van and contact the car wash directly to inquire about their size restrictions before attempting to wash it there. It's highly possible it won't fit, especially a longer model in an automated bay wash.
