In spite of the popularity and reliability of the SUV market, everybody can appreciate an affordable luxury sedan. When it comes to realistically-priced four-door sedans that fall under the luxurious category, BMW, Mercedes, and Audi have been the go-to names. It's safe to say all three of these German automakers have gone through their ups and downs, often alternating between the top three positions in this segment. While BMW and Mercedes have gone through tremendous changes, Audi remained relatively consistent. This is true for design and the overall image of the European luxury brand. We've recently reviewed the Audi A3, and it delivered as an entry-level luxury sedan. We also reviewed the S3, which redefined the idea of "fun-to-drive." We stepped up from the A3, and got into the driver seat of the 2022 Audi A4 S Line 45 TFSI Quattro to see if it's worth the money, or if you're better off going with a BMW 330i or a Mercedes C-Class.
