Classic Porsche cars are some of the most collectible vehicles on planet Earth, and the Porsche 911 in any form is regarded as one of the best sports cars of all time, so it should go against every instinct in a car person's body to turn one into a graffiti-covered rally machine. Not exactly.

Classic Porsches have been used as rally cars for decades, and people are also rather fond of covering them in paint. This rally-spec 1991 964-era Carrera 4, built by Alberto Vassallo and Agostino Rizzardi looks nothing like its original road-going self, and now features a modified engine, a custom suspension system, and enough attitude to take on the 2021 Tunisia Desert Challenge and the 2022 Dakar rally three times over.

This 90s Porsche has been fitted with a fully-adjustable suspension system with 35-inch tires and a full roll cage for added safety. Legendary motorsport brand Sabelt has taken care of all the harnesses and safety belts inside the car. The original flat-six engine and five-speed manual transmission are intact, but the engine has seen some modification and now produces a healthy 300 horsepower.

Keeping the flat six fed is a 42-gallon fuel cell (we can't imagine that this thing gets good mileage). The exterior is our favorite part of the puzzle: this Porsche features a period-correct graffiti paint job that harks back to the heady days of the Berlin wall and political broadcasts via spray can. The car has subsequently changed its look slightly, but still retains the spirit of Porsche.

This special 911 recently took part in the 2021 Tunisia Desert Challenge, and surprised many by how well it did, despite some technical difficulties.

"It was a magnificent experience, beyond all imagination. In 8 days we crossed the whole of Tunisia, passing through rocky landscapes and then moving into the deepest desert of the Sahara, we were always there to play for the absolute top 3 but, due to an electrical problem, we had to say goodbye to ambition to get on the podium even if by gritting our teeth we still closed the race in absolute P12. This is just the beginning, on December 28 we will start again, next stop: Dakar 2022," said Vassallo. We're keeping a close eye on this rad Porsche.
