I just looked at the f.s. thread he has in the MACA section for the recaro's.... There is a black seat with grabber stripes next to them so I would imagine they are the stock seats, so it looks like the seats are striped.
Yes the factory seats are striped. Black leather w/ blue stripes and the suede bolsters. Here is a picture of them when they were out of the car. These factory seats are now back in the car. I will try and get some interior and engine bay shots up this weekend. Unfortunately Tropical Storm Andrea is passing through my area so I wont have the car out for a day or two
