I would be EXTREMELY suprised if this car is factory original....
The steering wheel is aftermarket.
The one 1986 'slant nose delete' that I've seen 1st hand did have the oil cooler, and it also had a boost controler and the boost gauge in place of the clock - in other words it had some real 'special wish' options which included the boxed rockers and fender intakes.
All this aside, the current price of 32K seems pretty good for such a CLEAN, low mileage car, assuming it's the legit mileage. But many would steer a buyer away from such a low mileage car because lack of use is not good for a Porsche - they tend to leak and such if they sit around too much.
Oh, I do own a documented slant - an '87 505 code turbo coupe - I posted a pic in the 930 owner thread here.
