Dart Auto has been working on both of my Audi S4s for more than 4 years. Regular maintenance as well as performance upgrades have been skillfully handled in an acceptable time frame. Dave (the owner) has great prices and his head mechanic, Guenter, has handled small issues all the way up to complete Turbo upgrades on my S4. I've recommended other folks to Dart who have been happy with the results of work done on their Audis (A4). If you have a Porsche, Volkswagen or Audi, you can't go wrong bringing it to Dart auto for routine maintenance or significant repairs. Not to mention, they always seem to have a pretty tricked out Porsche race car on one of their lifts.
