its ok to ask for a car to be made if the car is unusual and isn't ordinarily going to be made in the course of the season.
what annoys people is when a new car is launched, and someone starts a thread asking for it to be made, and expects it to be released in a couple of days. of course its going to be made eventually, there's no need to badger people to make cars as soon as we see the first pictures of a new car.
i think this request is ok, to find out if someone has A) already made it, or B) is planning to do so.
RIP Jules, never to be forgotten. #KeepFightingMichael
