It's a brilliant marketing come-on, really. Who wants to climb into a GAZ-24, however appealing it might be to obscure-car guys, when you could sink into the all-enveloping sumptuousness of a Maybach 62? Need to get to Gorky Park quickly? A Porsche Cayenne outfitted with a meter and checkerboard detailing awaits at the curb. It's not just a fancied-up VW, still carrying the VR6 behind the Porsche crest, either. No, this Cayenne is a TechArt Magnum, packing enough horsepower to light Long Island.
