Would You Buy This Custom-Built Audi RS6 Allroad Quattro For $21k?

Have you ever thought of a possible combination between the C5 Audi A6 Allroad Quattro and the equivalent first-gen RS6 Avant? Well, a guy from Germany didn’t only dream of it but he actually built the world’s first “RS6 Allroad” which is now listed for sale on eBay for €17,999 ($21,106).

The custom build started from a used Audi A6 Allroad Quattro 2.5 TDI automatic from 2003, with a full 265,000 km (164,663 miles) in the odometer. While a lot of people would be unwilling to spend their money on a high-mileage vehicle with reliability issues, this is not exactly the case here. Actually, only 2,000 km (1,243 miles) have been added in its current form.

The whole drivetrain was removed from the car in order to make room for an RS6-derived biturbo 4.2-liter V8, producing 444 hp (331 kW / 450 PS) and 580 Nm (428 lb-ft) of torque. The automatic gearbox was also thrown away in favor of a proper six-speed manual, while the quattro permanent all-wheel-drive system was retained.

Besides the engine/gearbox combination, the owner added a few other parts taken from an RS6 (2002-2005) including the steering knuckle, rear axle, front and rear brakes, tank, pumps, exhaust, and ECU.

The air suspension of the Allroad is not known for its reliability, so a new KW V2 Coilover kit was fitted. However, the sports suspension means you don’t get any of the off-road credentials or the comfortable ride of the original car. Having said that, it wasn’t like you would leave the beaten track on the 20-inch forged rims that are borrowed from an RS5 and are shod in 255/35/R20 performance tires.

You already noticed the Sunflower Yellow exterior wrap contrasting with the plastic cladding all around the bodywork. The same color has been added inside for a matching look. According to the listing, the old leather upholstery on the Recaros will soon be replaced by Alcantara. The weird-looking carpets would probably look nicer in a children’s room but we guess that can be easily be fixed. Finally, the speedometer was also derived from an RS6 so you can see exactly how fast you are going.

The seller suggests that the project car still needs a bit of work in order to make it perfect. However, it is registered and is regularly driven on German roads. The question is this: would you buy this custom-built RS6 Allroad instead of an original RS6 Avant at a similar price?
