Never being able to leave a scab alone, I think I'll give picking it another try....
Yep, we all drive cars that look (to one degree or another) like "A" bodied Porsche speedsters-- so in a way I suppose you could call it posing. But I've never tried to convince anybody that it's anything other than what it is, and I think that this is what the law, purists, and most of us (deep down.... maybe VERY deep down) all have a hard time with.
I know Micky and I disagree on this, but I keep thinking that maybe it's because I haven't stated my case clearly enough.
For me (and for the law in Illinois), the problem isn't in driving a "fake"... it's in representing the car as something it isn't. I don't have Porsche badges on my car, because it isn't a Porsche-- some guys do, and that's OK with me as long as you don't mind engaging in in a 10 minute "explanation" to the afore mentioned divorced father of three and his 25 y/o girlfriend. I decided to forgo the pain, and just say "it's an Intermeccanica".
My car isn't titled as a Porsche 356, because it isn't a Porsche 356. All the Vintage, JPS, and Thunder Ranch guys have been told they can register their cars as VWs by the VIN on the pan, and 99% of them do. The problem is that (in most states) a cursory reading of the vehicle codes says this is wrong. LOTS of states have provisions for registering a replica as a replica, in the year it was meant to replicate. This is legal, and it's why I don't feel a bit of guilt about running antique tags-- the state knows what the car is, I've followed the letter and spirit of the law (even when I had to explain it to the lady at the DMV counter), and I'm eligible to save $78/yr on registration.
I don't want to fight a holy war over this. But the issue for me is fraud (and that's what misrepresenting a vehicle is)-- it's a really serious offense in most places, and one that will get you in a heap of trouble with "the man". My advice is: go to your state's DMV website, and read-up on replica and special construction titles. This hobby is littered with "folklore and common knowledge" about titles and registration. Most guys see know evil, hear no evil, and speak no evil when it comes to this issue. Wishing something was legal isn't the same thing as being legal.
If you do it the right way, you'll never regret it-- and you can lose that feeling in the pit of your stomach that you can only tell the cop, or passerby, or DMV half of the story.
