I bought an A4 convertible from them. Reasonable price. It was a 2007 so some issues are expected and we're found (small evap leak, oil burning, top doesn't go up or down) so, despite the fact that there were issues, they've been reasonable to work with and have accepted responsibility and honestly ores the warranty
Been doing business here for nearly 25 years, have purchased several cars for my entire family and use them exclusively for service. Couldn't be happier.
