I have a driver seat from a 2005-2007 Toyota Matrix that I brought home to replace my seat in a 03, but unfortunately, the connection is different. I've cleaned it several times, and it looks great. I'm selling it for $30.
I also have a dashboard from a 2003-2004 Toyota Matrix that I brought home with the intention of replacing mine. However, I never got around to installing it, and I've since sold the car. The dashboard is clean and in good condition, and I'm offering it for $30.
