New 2006 Audi S4 Base

Draped in Brilliant Red and showing only 29,936 miles, this 2006 Audi S4 Quattro Cabriolet is the kind of car that makes even seasoned enthusiasts grin like a teenager spotting their first turbo. Under the hood lies Audi’s legendary 4.2-liter V8—naturally aspirated, all-aluminum, and good for 340 horsepower. This engine doesn’t whisper; it sings a deep baritone symphony that crescendos toward its 7,000 RPM redline. Power is routed through Audi’s 6-speed automatic with Tiptronic, delivering a balance of smooth cruising and aggressive downshifts at your command. And thanks to Quattro all-wheel drive, this open-air S4 isn’t just a summer fling—it’s a year-round thrill ride, gripping tarmac with the confidence of a Bavarian mountain goat. The exterior radiates presence, with its Brilliant Red finish contrasting sharply against aluminum mirror caps, subtle badging, and a power-operated soft top that stows neatly at the push of a button. Inside, the cabin is pure Audi: a masterclass in understated luxury. Black leather Recaro sport seats hug you in all the right places, while carbon fiber inlays and brushed aluminum trim remind you this isn’t a boulevard cruiser—it’s a performance machine disguised as one. Dual-zone climate control, heated seats, Bose premium audio, and a navigation system bring modern conveniences into the mix, while the thick, leather-wrapped steering wheel keeps you tethered to the car’s intentions. Finding an S4 Cabriolet this well preserved, with such low mileage, is like stumbling across a vintage Bordeaux that hasn’t been uncorked—it’s rare, it’s intoxicating, and it only gets better with age. This is a car that blurs the line between daily driver and collectible, offering top-down thrills with four-season usability. If you’ve ever wondered what it’s like to drive your dream, this Audi is your invitation.
