Oh boy, Mystiques are even harder to find than Contours these days. I have access to Calgary and Edmonton, Alberta Pick N Pulls. I’m always willing to get parts and ship them. I recently found an SVT in Edmonton, I was able to snag some parts for mine, but by the time I got there the side skirts and headlights were gone and someone ripped the front bumper in half.
Also, if you do come across parts but are the wrong colour, you can always look into painting them. SEM makes a variety of plastic and vinyl spray paints for interior and trim parts.
