Construction Vehicles For Sale

There is a house down the street from us that has decided to make money from their yard. They roped off sections of their yard, and they are selling construction equipment. They have dozers, dump trucks, and Champion Rodders. I guess they will take a percentage of every sale or something. Sounds like a good idea, but they have yet to sell any of the four vehicles that have been sitting there for the past month. If people are like me, they would rather buy from a reputable dealer. I would want to know that the vehicle I am buying is reliable.
