Help me price my 930 for potential sale

Haven't posted much lately, but never miss a day reading these forums. Probably because my car has been down for rebuild for most of the time I have owned it. It's back on the road finally, but am considering selling (not yet committed and not distressed). Would appreciate opinions on what to list for and what to realistically expect.


1986 Porsche 930 / 911 Turbo, unique Ruf modifications, 41k original miles, fresh performance engine rebuild, rare Ruf 5spd transmission.

This Porsche was lightly modified by a Ruf authorized dealer in NJ when it was 1000 miles new. They shaved the raingutters (like the Yellowbird), added the rare Ruf 5 speed transmission, Ruf front mount oil cooler, Ruf polyurethane front spoiler, Ruf tachometer and speedometer, VDO boost gauge, Ruf intercooler (since replaced with bigger Kokeln) and Ruf boost control knob (since removed and not included). There were likely other Ruf items that were removed and sold before I acquired the car. The car had 37k miles when I bought it in June 2005, and I just completed a full performance engine rebuild designed to produce a reliable, but significantly more powerful car suitable for the street and the track. The engine has just finished being broken in and has less than 1000 miles. Total miles on car is now under 41k (not specific because I am driving it a couple of times a week).

I have well over $60,000 in the car, modifications and engine rebuild and have put less than 1000 miles on it since completing the work. This is the best way to buy a 930 Pictures following.
