Convertible Automobile Manufacture

Hello, I am trying to find out how many convertible automobiles are manufactured on a yearly basis. I am looking for numbers on both US and foreign cars. This will be very helpful toward my research into "ragtops!" Also, any links or email addresses to help me find this information would be much appreciated.

Thank you for taking your time and sending your reply to the question.

Thanks,
Louie
