Tips for Using Car Dealer Inventory Software

New data from Cox Automotive, NADA, BCG, and others confirm the wholesale-auction model no longer pencils for most franchised dealers. Buy fees have soared, transport costs grew by roughly a third, and condition reports haven't gotten any better, resulting in unexpected recon costs. Meanwhile, Manheim’s value index is still inflated above pre-COVID norms, so lane prices leave little or no front-end gross. 

Dealers have reacted fast: auction sourcing has fallen from a significant share of inventory in 2019 to a smaller share in 2023, while “off-street” private-party acquisition (PPA) has grown substantially. On the consumer side, a large portion of U.S. used-car transactions already happen peer-to-peer, and NADA expects that slice to keep expanding in the next few years. PPA—dubbed “Auction 2.0”—cuts average acquisition costs, turns inventory faster, and gives stores a shock-proof, hyper-local supply pipeline.

In short, the math just stopped mathin.

The big question is, how did the auction break? And will it ever be fixed?

2019 baseline → Auctions fed 27 % of dealer stock while private-party “off-street” buys were just 10 %. vAuto

2021-22 – Lane costs explode: buy-fees jump, and open-carrier rates hover near $1 / mile, turning auctions into a “last resort” for many dealers. DATAutomotive News

Oct 2021 – Inaccurate or optimistic condition reports forced Manheim to extend digital-buyer arbitration windows and add concierge inspection guarantees in 2021-22—a sign disputes were spiking. used car news

Feb 2023 – Manheim Index peaks at 234 (≈ $19k average), capping a 35%+ price surge over pre-COVID levels. Cox Automotive Inc.Wards Auto

2023 – Dealer sourcing flips: auction share sinks to 18%, off-street / PPA climbs to 15%. vAuto

2024 – Lane conversion can’t recover, averaging 58-64% vs. 70% pre-pandemic, proving buyers are staying out. Manheim

2025 – Index rebounds to 208.2 (+4.9% YoY); Sonic’s EchoPark lifts street-buys to 35% and AutoNation sources >90% internally to dodge auction premiums. Wards AutoWards Auto

Private-party deals already topped 10.3M in 2022 (~29 % of all used sales in 2022, 33% in 2023) and, per NIADA/Cox volume math, are on pace to hit the 40% mark in 2025. Wards Autoniada.com

Net result: all-in cost is up 36 % since 2019. Buy fees are up about 50% since 2019 (not including DealShield)

Paradigm Shift: Private-Party Goes Mainstream

This means roughly one-third of the auction share has evaporated in just four years, and 4 out of 5 cars now reach dealers through something other than a wholesale lane.

The structural break shows up first in 2021 and is cemented by 2023 as dealers realized the cost gap was permanent.

The “Auction 2.0”

The objective advantages of buying private party 

Lower entry cost: No buy fee, no gate fee, and shipping is usually zero. Faster time to line with sellers coming to you. 

Recon transparency: Dealers can road-test and lift the car pre-purchase, slashing surprise recon spend.

Unique inventory: Consumer vehicles are less commoditized than rental/fleet returns, supporting faster turn and higher retail grosses.

Built-in marketing: Each negotiation is a brand-touchpoint—hundreds of local conversations per day create future buyers at no additional ad cost.

Supply Resilience: A tariff, chip glitch, or strike can’t shut down the cars parked in your backyard.

From Selling Harder to Buying Smarter

Runaway costs, slipping vehicle quality, a fragile auction supply chain, and a market already sprinting toward driveway deals have converged into a four-way headwind that no dealer can afford to ignore.

Private-party acquisition isn’t the one-off sniping of cherry cars that it used to be; it’s the next-generation stocking channel—“Auction 2.0”—delivering margin, speed, and strategic independence exactly when dealers need it most. 

The numbers are clear:

1. +36% Cost Spiral: 

A mid-price auction unit that took roughly $16.6 K to land and frontline in 2019 now ties up ≈ $22.5 K, driven by higher hammer prices, fees, freight, and recon.

2. 33% Lane Volume: 

Auctions fed 27% of dealer inventory in 2019; today they supply just 18 %—one-third of the lane’s share has evaporated in four years.

3. 40% Market share

Private-party sales already account for roughly one-third of all U.S. used-car transactions and are on track to hit 40 % in 2025, according to NADA.

Stick with the lane and you’ll keep paying rising fees for generic, aging fleet units—while the best cars (and their owners) drive right past your store. Adopt the “Auction 2.0” framework, and you will turn local driveways into a profit center and future-proof your used-car department against the next supply-chain shock.

Takeaway: Now more than ever, winning in used cars starts with buying smarter, not just selling harder.
