38: Audi A4
An Audi is an entirely different beast than your average luxury car. Ultimately, it’s a performance-built machine. The A4 has always been a great entry-level luxury car that provided a great driving experience and a relatively luxurious interior. Likewise, the early 2000s A4 is one of the most popular models you can get (via Autolist).
It was available in sedan and wagon form, and it had one of the best engines you could get in this era. But the repair costs are also expensive and replacement parts for this car are very hard to come by. The turbocharged engine is not the most reliable engine to come out of Germany either. Because of that, repairs are costly.
