Audi B6 A4

The B6 generation Audi A4, sold from 2002 to 2005, represented a significant step forward in design and refinement. Penned by Peter Schreyer, its clean, Bauhaus-inspired lines have aged remarkably well. The B6 introduced a new platform that improved rigidity and driving dynamics, paired with updated engines like the venerable 1.8T four-cylinder and a new 3.0L V6. It was offered as a sedan, Avant wagon, and Cabriolet, firmly establishing Audi as a direct competitor to BMW's 3-Series.

Collectors and enthusiasts are drawn to the B6 A4 for its blend of modern usability, analog feel, and affordable entry price. The highly tunable 1.8T engine, available manual transmissions, and Audi's signature Quattro all-wheel drive system create a desirable package for a daily driver or weekend project. The Ultrasport package, with its unique body kit and suspension, is particularly sought after for its factory-enhanced looks and performance, bridging the gap to the V8-powered S4.

The market for the B6 A4 is mature and value-driven, with an average sale price of just over $8,000. The wide price spectrum reflects the car's dual life as both a cheap used car and an emerging modern classic. Project cars can be found for very little, while pristine, low-mileage examples with the Ultrasport package and a manual transmission regularly sell for over $15,000. Avants and well-documented cars command a premium over standard sedans.

Prices for sold examples range from $405 for project cars to $16,000 for pristine, low-mileage variants.
