XPost - Shipping a car cross country?

Awesome news, DH's boss just surprised us and told us that his company is willing to pay for the majority of our move (previously this wasn't the case). Now that it is and we already had all the money saved up for what we could afford (and they're extending our budget a little bit) we were thinking we may want to make our lives easier and have them ship our cars rather than drive both cross country.

Can anyone recommend a company they used to ship their cars?
