These auctions are strictly for two reasons: speed and liability.

Walk into a major auction like Manheim or Adesa and you’ll find a symphony of controlled chaos.

Sales between "merchants" (dealers) are subject to fewer regulations and no sales tax at the point of purchase, keeping the administrative burden low.

Almost everything is sold without a warranty. If a dealer buys a "lemon" with a blown transmission, they own it—no returns, no excuses.

Multiple lanes run simultaneously as auctioneers chant in a staccato rhythm that requires a trained ear to follow.
