Keanu Reeves definitely made our naughty list this Christmas for what he did with one our favorite cars. As you can see from these pictures, he strapped a Christmas tree to the roof of his Porsche Carrera 4. Shame on you, Mr. Reeves!From what we can tell, the car in question is a 1996 911 Carrera 4, a hot sportscar at the time (and today). The Porsche 911 Carrera represented the "base model" of the 993, and was available in rear and all-wheel drive versions. It was equipped with the naturally aspirated 3.6 liter M64 engine, further developed from the 964 and combined with a new dual-flow exhaust system now incorporating two catalytic converters.Unlike the Type 964, Porsche deleted the "2" from the rear-wheel drive "Carrera" name tag. But among enthusiasts, the differential between the rear-wheel and all-wheel drive variants of the Type 993 Carrera they were (and still are) commonly referred to as "C2" and "C4", respectively. The extensive options list offered at the time included up to five different styles of wheels, various suspension set-ups, at least three different seat styles (comfort, sport, racing), uncountable upholstery options including the possibility to have almost any interior element of the car covered with leather, wood or carbon fiber, and various hi-fi systems including digital sound processing.Judging by how dirty the car is, Keanu really doesn't care. It must be nice to have money, what we see as an awesome ride, he treats it like a rat-mobile. It doesn’t help either that the tree is strapped down with a string that goes through the inside of the car.
