I have a MK3 MX5 (also known as an NC) as well and am part of the NC Europe club. If you promote zip buddy's to these guys, as they have a logo, I bet a few people go for them https://www.facebook.com/groups/nceurope.club/
Robo is a complete hero and has come through for me with the new bus drawing. Thank you, Robo. I've done the design work for half a dozen colours to start and will be printing these this afternoon.
Happy to do a second run of additional colours (Nearest Pantone PMS reference will help get yours included )
