Why did the DMV send me a notice to renew my registration or that my registration lapsed after I sold my car through Caramel?

In some cases you need to notify your DMV that you’ve sold your car, which you can often do on their website.  If your DMV asks you for an address for Caramel, you can use: 

Caramel Dealer Services, LLC: 2829 Great Northern Loop, Suite 214, Missoula, MT 59808.
