About the Audi RS4 Cabriolet
The Audi RS4 Cabriolet was produced from 2006 to 2009 as part of the B7 generation, powered by a naturally aspirated 4.2-litre V8 engine producing 420bhp. This four-seater convertible combined Quattro all-wheel drive with a 0-60mph time of 4.9 seconds, making it one of the most practical yet exhilarating performance drop-tops of its era. The RS4 Cabriolet featured aggressive styling with flared wheelarches, 19-inch alloys, and a well-appointed interior with Recaro sports seats and premium materials throughout.
What Affects the Price
Mileage is a significant factor, with lower-mileage examples under 50,000 miles commanding premium prices above £30,000, while higher-mileage cars over 100,000 miles typically fall below £15,000. Service history is crucial - cars with full Audi main dealer history or specialist servicing hold considerably more value than those with incomplete records. Condition matters significantly given the age of these vehicles, with pristine examples featuring original paint, unmarked interiors and no mechanical issues fetching top prices. Specification variations including Bang & Olufsen audio, satellite navigation and the desirable Carbon Atlas pack can add £2,000-£5,000 to values.
Buying Tips
Inspect the V8 engine thoroughly for signs of oil consumption and check for the common carbon build-up issue that can affect performance - budget £500-£1,000 for carbon cleaning if required. The Quattro system and DRC (Dynamic Ride Control) suspension are complex, so ensure all-wheel drive operates correctly and the adaptive dampers function without warning lights. Check for corrosion around wheelarches and door bottoms, particularly on cars used year-round, as repairs can be costly. Verify the convertible roof operates smoothly through complete cycles and inspect the rear window for delamination. Demand comprehensive service history with evidence of regular oil changes every 9,000 miles, timing chain inspection, and gearbox servicing every 38,000 miles for the manual or 40,000 miles for the automatic.
