According to the CarFax license plate check, this is a 1986 Pontiac Parisienne Brougham. While I’m not the most knowledgeable on 80's cars, I’m still surprised I haven’t seen at least one of these or heard them mentioned online. I didn’t get to find the owner, but I think it belongs to a friend of the Focus’ owner.
UPDATE: Oh my gosh. I saw another one. I told the people inside about what happened yesterday, and they said these are hard to find. This one is an ‘85.
