I can only apologise for any inconvenience to you. You will never get
another e-mail from www.citroen-owners.com

We are a group of dedicated mechanics and auto technicians who have
decided to share information in a fresh and innovative way by hosting a
free tele seminar every Thursday. We think the content is very appealing
to garage owners. Your email address was supplied by PollenUK.

Best Regards
