Abstract: The disclosed vehicle stands have a base, a top plate, and a mechanical stop on the top plate that hold a vehicle in a secure, suspended position above a surface, such as the ground or a floor. The top plate can be removable from the base. The base has two legs that extend away from the top plate. The top plate can be flat or contoured to compliment a shape of a vehicle resting upon it. The top plate can include additional securing elements, such as a friction that on a surface that contacts a suspended vehicle and a locking mechanism that attaches to the suspended vehicle. Multiple vehicle stands can be used together. Two of the multiple stands can be connected by a cross-bar that extends under the vehicle as it is suspended above the surface by the two respective top plates.
