Not purchase price related, but dealer related. It's not that easy, at least to do it legally. Have to actually get the license, make sure your property is zoned properly, carry insurance, research each vehicle, be prepared for scams and shady actions by the auction employees and other dealers, the vehicle is NEVER 100% as described, actually go get it (truck and trailer or pay to have it delivered), dealing with the idiot general public when selling, keep up with dealer plates, and maintaining the license. It's not all rainbows.
