Over the weekend I penned a screed calling baby boomers to task for embracing retro style over the the values that made the revolutionary cars of their era so revolutionary [editor’s note: there’s nothing like having a carburetor on your 35 year-old motorcycle magically fix itself to inspire faith in old, simple machinery]. The new New Beetle was square in my crosshairs over the weekend, but it’s hardly the only example of boomer retro-madness. Another favorite for nostalgic boomers are the legendary muscle cars that marked the high-water point for Detroit thunder, and this feverish demand combined with limited original runs have run the prices of famous muscle cars into the Barrett-Jackson stratosphere. It’s also inspired a legion of knock-off and replica manufacturers, who see huge money to be made by aligning supply with demand. They, in turn, have inspired a number of huge lawsuits from the original creators of the limited-edition legends. Carroll Shelby’s prolific legal battles against creators of Cobra replicas have given him the reputation of being a guy who never met a buck he didn’t like, and now GM has joined the Shelby legacy, suing Mongoose Motorsports for daring to produced replicas of the 1963 Corvette Grand Sport roadster.
