Yes. You can check the marketplace. You can also ask in the wanted section:

I am not sure what you have been doing. But I would guess there’s something wrong with the approach. I signed one 3 months ago (effective $109/month) just by simply messaging a dealer from the LH marketplace. I didn’t even need a car so I offloaded an older lease and grabbed a new one. If you don’t want the hassle of messaging dealers your offer, you can just get a pre-negotiated deal or get a broker advertised deal like I did.
