Okay, it's basic business. Not going to act like I "know it all", but I'm just going with the basic principle of supply & demand. It's a well (and professionally) tuned car, and finding a Scirocco in North America is incredibly rare.
Sirocco's are cool cars to probably about less than 1% of the population in North America. And 1% of that 1% probably has the money to buy this car. People who drive VW don't do so because they've got 200 grand to blow on cars, just saying.
