Indeed, as you can see, Iwan's 504 is no longer 4 doors, but 2 doors! This does change the look of the car, doesn't it?
The front doors look quite longer to me than the normal ones. The rear doors are replaced with a fixed window. I don't think that the body has been shortened, but maybe Iwan will contradict me?
The side blinkers and the alloy wheels are also specific.
Of course, the engine has also been modified, to best fit the new shape of the car. Iwan lists the modifications made: "porting, new valvetrain, electric fan conversion, upgraded ignition and two-door conversion, etc. Induction is standard (solex 32/35 SEIEA). Second gear ran to 100kph, 3rd to 140kph and 4th is not tested yet. it's fast!"
Notice also the 2 other 504s in the background... That makes a nice garden!!
