Our Services

What We Offer Dealers

We take wholesale off your plate. Submit your inventory, and our team manages the entire auction process from start to payment.

Auction Placement
We place your vehicles in premium auction lanes at Manheim and our partner auctions to maximize exposure and final sale price. Our lane selection is data-driven to match vehicle profile to the right buyer pool.
Vehicle Listing & CR
Professional condition reports and photography for every unit. Detailed, accurate CRs build buyer confidence and reduce arbitration risk — protecting your bottom line after the sale.
Fast ACH Payment
Once your vehicle sells and title is submitted, we process payment via ACH directly to your account. No waiting on checks, no chasing funds — clean, fast, and transparent.

From Our Dealer Partners

What dealers say

★★★★★

"Diamond Auto Group took our aged wholesale units off the lot and had them moved through auction within two weeks. The lane placement was excellent — we netted more than we expected on several units."

Ben R.
General Manager, Premier Auto Group
★★★★★

"We send over a batch every month now. The condition reports are thorough, the listing photos are clean, and the ACH hits fast after the sale. Couldn't ask for a smoother wholesale process."

Omar M.
Used Car Director, Valley Motors
★★★★★

"The flat-rate pricing made it easy to budget. No surprises, no hidden fees. Diamond Auto Group is our go-to wholesale partner for anything we don't want sitting on the lot."
