Below is the reply he received and there is no evidence of differentiation between mazda and eunos, so it may be worth a try?? Olive branch anyone??
Comments please, and try to be civil about it

Hi Ollie
Many thanks for your email, which I received this morning. I am very interested in continuing to build a productive relationship between MX5 Ireland and Mazda Motor Ireland and I hope that we can work together on this one for the purposes of mutual gain.
We would be happy to sponsor MX5 Ireland directly for inclusion of the ten cars and will endeavour to gain a defined zone for you to pull together a dedicated MX-5 paddock.
I would ask that you would commit to the following:
· Provision of the Cars
· Your co-operation in the use of underwheel flags (see attached)
· We would also like to position windtalkers next to your display (big picture stands – see example attached) to celebrate 20 years of this classic true sportscar.
· If there is a cavalcade drive at the event and we would like to brand a top and tail car or a lead car and encourage a drive by if possible.
I look forward to hearing from you.
Kind regards.

This could be an opportunity to start communication between ourselves an mazda Ireland, even the Northern Troubles necessitated people talking to each other, so please consider giving this your support.

PS I do not intend to offend anyone by equating our differences with Mazda with the past events in Northern Ireland

PPS more info on the event itself...sorry about short notice by the way
