Car Gurus Pricing Model?

Hi! I’m trying to understand a little more about how CarGurus makes money, specifically on the dealer side.

Does anyone know what the different dealer subscription/package tiers are, what features are included in each, and/or roughly how much CarGurus charges for each tier?

I’d also be curious if pricing varies based on dealership size, inventory, location, or number of listings. Any insight from dealers or people familiar with their pricing model would be really helpful. Thanks!
