TO be honest, I hate the way red interior cars smell. Every car I've been in that has a red interior smells the same for some reason, and it's a unique smell compared to other cars. No worries though, what I would do it try to get a shift knob from a black interior car it's amazing how much a changed shift knob can do to the interior. I went from black to a red Nardi one, and I switch them off when I can.
