TrueCar, Edmunds, and Kelley Blue Book are the three tools most car buyers use to research pricing before walking into a dealership.
They're also all dealer lead-generation businesses.
That doesn't mean they're useless — each provides real value in specific situations. But you need to understand their actual business model before you rely on their numbers to negotiate a $35,000 purchase.
Charges dealers $299–$399 per vehicle sold to a TrueCar user. When you request pricing or enter your information, you become a lead sold to participating dealerships. The dealer knows you're coming before you arrive.
- Quick read on what a specific new car is selling for in your region
- Verifying whether a dealer's quote is in a reasonable range
- Finding dealers who've committed to TrueCar pricing
TrueCar's "savings" are shown against MSRP, not against what's actually negotiable. "$1,200 below MSRP" sounds good until you realize the vehicle may have been negotiable to $3,500 below MSRP with the right approach. TrueCar went private in 2026 in a $227M buyout — new direction unclear.
Quick sanity check on whether a dealer's quote is in range. Not a negotiation tool. Don't submit your information if you want to avoid dealer calls.
Makes money through dealer advertising, sponsored listings, and lead generation. Dealers pay to be featured prominently. Edmunds' financial relationships with dealers create an incentive to present pricing that satisfies both sides.
- True Market Value (TMV) is genuinely useful — it reflects real transaction prices, not just listed prices
- Incentives section is thorough: manufacturer rebates, low APR offers, cash-back deals
- Best editorial content of the three: vehicle reviews, reliability guides, car buying advice
TMV is an average — half of all buyers paid less. Edmunds shows you what transactions happened. It doesn't help you understand the dealer's actual cost or how much room exists between invoice and transaction price.
Solid starting point for market pricing. Best for incentive research. Pair with invoice data and local market analysis for actual negotiation.
Owned by Cox Automotive, which also owns Autotrader, Manheim auction houses (the largest wholesale auto auction network in the US), and vAuto — the inventory management and pricing software used by thousands of dealers. Cox Automotive's business succeeds when dealers succeed. This is the most significant conflict of interest of the three.
- Trade-in benchmarking — KBB trade-in value is widely used by dealers, gives you a reasonable floor
- Used car pricing — most granular pricing across conditions
- Brand recognition — when you cite KBB to a dealer, they know what you're referencing
When the same company sells pricing software to dealers (vAuto) and provides pricing guidance to buyers (KBB), there's an inherent tension. KBB's Fair Purchase Price tends to run higher than Edmunds' TMV — and gives you a price to feel good about, not a price to negotiate from.
Trade-in floor estimate. Used car pricing reference. Brand-recognition tool when quoting a number back to a dealer.

What none of them tell you.
TrueCar, Edmunds, and KBB show you what buyers paid. Car Lot Wizard tells you what the dealer paid — invoice, holdback, lot time — and gives you the word-for-word scripts to use it.
The Honest Recommendation
Use all three as free research tools — but don't mistake them for buyer advocates.
For a used car: KBB trade-in value gives you the floor your dealer starts from. Edmunds private party pricing gives you a market range. CarGurus "Fair Deal" factors in days on market.
The tools above tell you what people paid. The question to ask is: what can I actually get this car for? Those are different numbers.
Combine these market averages with the dealer's actual cost structure — invoice price, holdback, days on lot — and you'll negotiate from a position most buyers never reach.
Same car. Very different position.
KBB tells you a $42,000 car has a "fair purchase price" of $40,500. Car Lot Wizard tells you the dealer paid an estimated $37,200, it's been on the lot 74 days, and here's the script to open at $38,400.
