I called German Car Specialists a month or two after the dealer quoted me $2300 for the 108k service (timing belt) and ~$2000 for a new catalytic converter on my 2003 Audi A4. Despite always doing regular oil changes and scheduled maintenance, I decided I was willing to wait just a little while longer given the cost. At this point, I had ~109000k miles on my car. I didn't leave a message but Tony still called me back on his day off. As usual, his rates were much better than the dealer but I told him I still might wait a few weeks - i.e. I had a busy schedule, blah, blah, blah. He explained to me the importance of the timing belt, what could happen if it snapped (total my engine) and how this service is now done at 75000k miles. Not realizing this prior, I made an appointment for that Monday and crossed my fingers I would make it there. On the way back to pick up my car, the shuttle driver said oh, you're the one everyone is referring to as the lucky car . Then Tony showed me a very large gap in the timing belt where eight or so teeth were missing and how it all works. And oh how lucky I was….I had no idea until that moment. By chance, if I had stopped/started my car and the stripped belt portion landed just so - bye-bye engine. A HUGE thanks to Tony (and his team) for saving my engine and my wallet! Without his pro-active follow up and extra care in explaining everything to me, I can confidently say my bill would have been three to four times higher than what I was trying to avoid. I will take my Audi to German Car Specialists from now on….no exceptions!
