I am the Mazda Speed Sales rep. for Walser Mazda in Burnsville MN. I am allotted 20 of them so far, and would be happy to assist anyone who is interested. You can email me with questions at xxxx@walser.com. Otherwise if you have more pressing concerns feel free to give me a call at 866-887-xxxx and ask for Cal. If I'm out just leave me a msg, and I'll return your call as soon as possible. I just returned from the MS-P seminar in Chicago, it was pretty awesome. I also got a sneak peak at the Mazda 6. They said that they're revising the HP on the 6 cy to 230!!
