Old and New Cars in Puriscal

old car in Puriscal

new car with water tube on top
The contrasting old and new cars. Note the water tube on top of the new car. I began noticing these a few years ago. When I first asked what they were for, people would giggle and say they were full of guaro. The internet tells me they are for washing mud off vehicles or even for a quick shower. I'm curious to know if these are as popular in other parts of the world as they are here.
