Registration of 2008 GT500 Convertible

I have been looking for sometime for a very low mileage Shelby GT500 Convertible. I found one this week and have scheduled a time to go look at the car. I asked if the car was registered with Shelby America and was told that he never registered the car when it was purchased new. Is this a big deal that the car was not registered when it was originally purchased? The car is in perfect condition but I was looking for one that had been registered when it was purchased. Also if I were to purchase the car and register it does that matter that it was not registered when it was new. I plan on keeping the car for a very long time but want to make sure I make the correct purchase.

 

Thanks for the quick response. I did know that I could register the car but wanted to make sure that it was not that big of a deal if it were not registered with the original owner.
