I voiced my opinion here just a few minutes ago, I have since spoken with Good Speed in Scottsdale. We had a at length conversation about my issue. They answered all my questions about the things I said. It does seem I spoke to soon. I won't go into detail because of the complex nature. But for good speed to contract me and truly explain why, says a lot about their company and honesty. Good Speed im sorry for making a quick off the cuff review and I will continue to be a customer for my Audi S4. Thank you and I apologize again for the misunderstanding.
