i was looking to buy a Datsun 280Z and i wanted to know some more of the details about the car, the history of the car and how well it performs. There is also this cool thing on the back windshield that i dont know how to describe, but heres a picture: http://upload.wikimedia.org/wikipedia/commons/5/51/79-83_Datsun_280ZX_rear.jpg ......Can this piece be added to the car if it does not already have it on? Thx for the help guys.
