Paperwork to Sell My Car

Hello,

I moved to the north coast a year and a half ago, and bought a vehicle from a used car dealership. They did all the paperwork for me and I just needed to sign on the dotted line. I know there have been horror stories about buying from dealerships, but everything actually went quite well for me, and the car's been great, but that's neither here nor there.

I'll be leaving the DR unexpectedly in 2 weeks, and need to know exactly what paperwork I need to fill out in order to sell the car before I go if I do it privately? And, dumb question, but is the certificado de propiedad de vehiculos de motor the same as matricula?

Thanks!
Tyson

Thanks William, I appreciate it. I have a few people interested already, so wasn't really planning on selling it here... Mostly just want to make sure I have the paperwork in order before I start letting people see/test drive it.
