Impressed and shocked (in a good way)

My thanks and heartfelt gratitude to Rudy and his mechanic for helping me find a VERY annoying rattle in a recently purchased used Audi from another car dealership. I had the car at 5 different places (tire shops, shocks, exhausts and auto works) and none of those could get to the bottom of the rattling noise!.. I contacted Rudy and he was so kind to let me bring the car for them to check and within 30 minutes the problem was found and rectified. I was expecting a hole in my wallet, but it was all done for free! You don't hear that word anywhere anymore nowadays, especially from car dealership service centers. Thanks again and I'm now officially impressed with the customer service from Audi Century City.
