I agree that keeping up with the latest models would be integral to the Saleen brand. Look, we're not selling off the shelf Honda Civics here. A Saleen vehicle is a discretionary spend and when someone is purposefully plunking down extra $ to enjoy their ride - splurging for a prior model is NOT the sell.
While not ideal to the bottom-line - it's a reality of the automotive marketplace, the adage of innovate or die applies here. There will be those who enjoy the previous version - by all means continue to sell to the purist (I probably fall in this category myself). There are those who MUST have the latest ride, let's serve them just as vigorously.
Just my .0002 cents
