The A4 is undeniably a good car. None more so than the third generation, or B7 A4. Regardless of the specification you’d ordered it in, it was a handsome, well-built and comfortable car. Whilst many were ordered with militarily reliable PD diesel engines, a few left Audi’s production line with something a tad more spicy.

Both of Audi’s “hot” variants of the B7 were made available with a 4.2-litre V8 engine. But that is about where the similarities end, because while the S4 had to make do with just 340bhp, the RS4 had a whole VW Polo’s worth more power. Combine that with revised suspension, brakes, wide arches and and host of interior upgrades, and the S4 really look rather tame.

The B7 RS4 was produced in more limited numbers, with just 5% of the production being Cabriolets. That makes this car, which was supplied new in May of 2007, a particularly rare beast. It’s finished in Phantom Black over a Silver interior, and sits on its original 19” RS4 alloys.

Those wheels fill the enormous DTM-inspired arches perfectly and hide massive two-piece brake discs with subtle black branded RS brake callipers. At the front, there are optional adaptive Xenon headlamps, and at the rear, Audi’s trademark RS oval exhaust tips.

Even nearly 20 years ago, Audi built great interiors. They’re designed with logic and ergonomics in mind, whilst utilising high-quality materials and tactile switch gear. Take the steering wheel, three spokes, trimmed in perforated leather and with carefully bolstered padding, without going all out flat-bottom.

It’s not lacking in equipment either, with dual-zone climate control, heated electrically adjusted seats and Audi Navigation Plus, for which CarPlay upgrades are available in the aftermarket. Offering a usable upgrade without compromising the car’s originality. The interior is topped off by a particularly rare option, fine myrtle nutmeg wood trim, which adorns the dash and door cards, adding a touch of class.

Of course, the greasy bits are what the RS4 is really about. The aforementioned 4.2-litre V8 produces 420BHP and is paired with a 6-speed manual gearbox and Audi’s infamous Quattro all-wheel-drive system. All that works together to deliver you to 60 in under 5 seconds, which is mighty impressive.

Despite having covered just 36,069 miles, this car has been meticulously maintained by its two owners, both within the Audi main dealer network and with specialists.

Audi will never build a car quite as bonkers as this again, in part because they have now retired the A4 name, but mainly because demand has shifted away from large capacity naturally aspirated engines. Despite what us enthusiasts write on internet forums and Facebook pages.

But that leaves you with a unique opportunity to own a relic, a snapshot in time when the cars we could buy were uncompromised, fitted with astonishing engines and Grammy-worthy soundtracks. Finding clean examples of B7 RS4s has become increasingly difficult; this, though, is a great one.
