We recently made a visit to the Mercedes-Benz Classic Car Center in Irvine, California, to check out this restoration and retail facility. Located adjacent to a cluster of auto showrooms, it looks like just another modern dealership. But the cars inside are anything but modern. For starters, there's a 1954 220 Coupe out front. Once inside the building, you'll be greeted by some of the most desirable models from Mercedes' glorious past. Gullwings and Patent-Motorwagens, SLRs and Pullmen.
