If you're a dealership evaluating lead providers, the pricing isn't always straightforward. Between per-lead charges, monthly subscriptions, setup fees, and annual contracts, the true cost of acquiring a vehicle through third-party leads is often 3–5x what the advertised "per lead" price suggests.
This guide breaks down the real numbers for every major lead provider in 2026, including the hidden costs most vendors don't highlight upfront.
The Complete Cost Comparison
| Provider | Cost Per Lead | Monthly Subscription | Cost at 100 Leads/Mo | Leads Shared? | Contract |
|---|---|---|---|---|---|
| KBB Instant Cash Offer | $25–$75 | Included in Dealer Program | $2,500–$7,500 | Yes — 3–5 dealers | Annual typical |
| Cars.com | $30–$60 | $399–$1,299/mo | $3,399–$7,299 | Yes — marketplace | Annual typical |
| Autotrader | $25–$50 | $500–$1,500/mo | $3,000–$6,500 | Yes — marketplace | Annual typical |
| CarGurus | $25–$50 | Dashboard fee varies | $2,500–$5,000+ | Yes — marketplace | 6–12 months |
| TrueCar | $20–$45 | Varies by market | $2,000–$4,500+ | Yes — marketplace | Annual typical |
| AutoRelay | Flat fee (unlimited) | $500/mo | $500 | No — 100% exclusive | Month-to-month |
The Hidden Cost: Shared Leads
The per-lead price is only part of the story. When a lead provider sends the same lead to 3–5 competing dealers, your close rate drops dramatically. Industry data shows that shared leads close at roughly 5–8%, while exclusive leads close at 15–25%. That means:
| Metric | Shared Leads (KBB/Cars.com) | Exclusive Leads (Service Lane) |
|---|---|---|
| Leads per month | 100 | 100 |
| Close rate | 5–8% | 15–25% |
| Vehicles acquired | 5–8 | 15–25 |
| Monthly cost | $3,000–$7,500 | $500 flat fee |
| Effective cost per vehicle | $425–$1,500 | $20–$33 |
KBB Instant Cash Offer: What Dealers Actually Pay
KBB Instant Cash Offer (ICO) is one of the most recognizable names in consumer vehicle valuation. For dealers, the program works like this: a consumer enters their vehicle on KBB.com, receives an instant offer, and the lead is sent to participating dealers within a geographic radius.
- Per-lead cost: $25–$75 depending on market and vehicle type.
- Lead exclusivity: None — the same lead goes to 3–5 dealers in your area.
- Customer intent: Mixed — many are just curious about their car's value, not ready to sell.
- Follow-up required: Manual. Your BDC needs to call/text/email before competing dealers.
- Annual spend (typical): $30,000–$90,000 for a mid-size dealer.
Cars.com: Subscription + Per-Lead Double-Hit
Cars.com requires both a monthly subscription (for dealer listings and visibility) and charges per lead. The subscription ranges from $399 to $1,299/month depending on market size and package. Per-lead charges of $30–$60 apply on top.
- Monthly subscription: $399–$1,299 (required for presence on the platform).
- Per-lead cost: $30–$60 on top of the subscription.
- Combined cost at 100 leads: $3,399–$7,299/month.
- Lead quality: Consumers actively shopping — but shopping at several dealers at once.
- Best for: Dealers who need listing marketplace visibility. Less effective for acquisition-focused strategies.
Autotrader: Premium Pricing, Shared Results
Autotrader, owned by Cox Automotive (same parent as KBB), operates a vehicle listing marketplace with similar economics. Monthly subscriptions of $500–$1,500 plus per-lead fees of $25–$50. Many of the same consumers are on both Cars.com and Autotrader, so dealers often see overlap.
CarGurus: Transparency That Cuts Both Ways
CarGurus differentiates by showing consumers whether a dealer's price is a "Great Deal," "Good Deal," or "Fair Deal." While this drives traffic, it also trains consumers to negotiate harder, compressing your margin before the conversation even starts. Leads cost $25–$50 each, and they're shared across the marketplace.
TrueCar: The Price-Transparency Tradeoff
TrueCar shows consumers what others paid for the same vehicle in their area, creating downward price pressure. Leads are $20–$45 each and shared. The model works for volume dealers willing to compete on price, but it's not an acquisition strategy — it's a sales tool with thin margins built in.
The Alternative: Service Lane Acquisition
Service lane acquisition platforms like AutoRelay take a fundamentally different approach. Instead of buying leads from an external marketplace, you're engaging your own service customers — people who already have a relationship with your dealership.
- Cost: Flat monthly fee ($500/month for unlimited leads).
- Exclusivity: 100% — these are your customers, not shared with anyone.
- Lead source: Your service lane (1,500+ vehicles/month at a typical franchised dealer).
- AI follow-up: Instant automated SMS responses, 24/7.
- Close rate: Significantly higher than shared leads — exclusive leads convert at multiples of shared ones.
- Contract: Month-to-month, 30-day free trial, no credit card required to start.
Cost Per Acquisition: The Number That Matters
The most useful metric isn't cost per lead — it's cost per acquired vehicle. A $30 shared lead that takes 15 touches and closes at 5% is far more expensive than an exclusive lead from your own service lane that closes at multiples of that rate.
| Provider | Monthly Spend | Vehicles Acquired | Cost Per Acquisition |
|---|---|---|---|
| KBB ICO | $4,000–$7,500 | 5–8 | $500–$1,500 |
| Cars.com | $3,399–$7,299 | 5–8 | $425–$1,460 |
| Autotrader | $3,000–$6,500 | 5–8 | $375–$1,300 |
| AutoRelay | $500 | Significantly more | Fraction of competitors |
How to Choose the Right Lead Provider
The right answer depends on your dealership's goals:
- If you need marketplace visibility for retail sales: Cars.com or Autotrader for listing presence.
- If you need low-cost vehicle acquisition: Service lane acquisition (AutoRelay) for exclusive leads at a flat fee.
- If you're spending $5,000+/month on shared leads and want to cut costs: Replace or supplement with a service lane platform.
- If your BDC is overwhelmed: AI-powered platforms handle outreach 24/7 without adding headcount.
Many dealers run both — a marketplace listing for retail sales and a service lane platform for acquisition. They're not competing strategies; they serve different goals.
