OK, so what, precisely, is a Curbstoner?
Here’s some background:
You know that place on your commute that always has a bunch of cars for sale? the patch of waste ground by the stoplights?
That’s almost certainly a curbstone site. Curbstoners are unlicensed vehicle dealers, called as such because they tend to park a selection of cars for sale in popular areas along the curbstones. They operate in this way because a private sale of a vehicle is not covered by the legal restrictions that a dealer must abide by.
Why are they bad?
