I'm a forum member and would now like to join the MX-5 Owners Club ?

This is what you need to do:

Upgrade to full MX-5 Owners Club membership now!
How do I upgrade from forum only membership to full membership?

Please do not use the "join online" link on the website if you are already a forum member.  Instead, please telephone Membership Administration on 0845 601 4231 between 9.00am and 5.00pm, Monday to Thursday.  You will need a note of your forum membership number and to have your credit/debit
card to hand.
