Ok, I'm a complete newbie. Other than lurking and sponging I have almost no Porsche knowledge. I've been a vette guy but just got kind of tired of them and sold off my last one a month ago. So I found this car and it lives less than 20 miles from me. I have always loved the slant nose and this one makes me weak at the knees, but I just don't know how to access its value. It is a conversion that started with a 77 911, the motor (3.3 Turbo), Trans (turbo 4 spd), suspension and brakes came from an 88 turbo, the interior and top are full power and out of a 94. All Body conversion parts are factory steel. The conversion was done in 97 by a Beverly Hills Doctor who spared no expense and reportedly dropped 60+K into the project. The mileage of the original 911 is unknown, the mechanicals had 40K upon install and only 45K now. The car was completely stripped to bare metal and repainted in 2004 at a cost of 10K then the Dr. sold it to the guy who owns it now, he is selling it along with a Ferrari 308 to pay for his daughter's wedding - he states he has only driven the car about a dozen times in the past 3 years as it is one of 5 "toys" - unfortunately there is no documentation of the conversion project, apparently all records were lost during a move. He wants 24K for it - it looks incredible and runs great but how do I know if it is worth it? I would appreciate any advice from those of you more knowledgeable than I. Thanks.
