The value of car brokers to private buyers is that they can channel sufficient orders through a single dealer for that dealer to obtain volume discounts that are then passed onto individual buyers.

If you are buying a fleet you are already in a negotiating position, but it depends on the size of the fleet. Big fleet, adopt a single make policy and negotiate your own big discounts through the same dealer.

Small fleet, use a broker such as www.drivethedeal.com/ Or consider leasing because the lessor will channel large orders through dealers and get the volume discounts. Try www.dsgauto.com
