You can just let them know that the 951 was faster and better handling as the same year carrera. They may be cheaper, but the are every bit as Porsche. Some market analyst seem to believe that the 944/968 died out because they had become a better performing car for much less money. Remember the 968 Turbo S that was made??? It had 50/50 weight distribution, and 0-60 in ~4.0sec with a top end of almost 180mph. I don't think there are too many 911's that can match that. Also, it is easier(cheaper) to buy a 951 and make modify it than to mess with a NA 911. I love my 951 and will never get rid of it. Someday I might have a 911 Turbo, but sitting next to it in my garage will be my 951
