Are there any dealerships in Houston that will pay extra over a Carmax offer?

I am going to sell my car come mid-May because I'm moving to a city where I won't need it. I could use the extra cash for moving/living expenses. Carmax gave me a great offer and I'm wondering if there are dealerships that have incentives for you to sell it to them instead. I found one in Austin, but was curious about any in Houston, since it will make it easier and I wouldn't have to do the extra drive.
