For some reason there is something not quite correct about this car.

The manual seats are nice but are they correct?

 

Looks about right to me. Must have the Competition Group option offered in '81-82. That's explain the 'S' gear.
Seats look right too. They're 930 seats but were used in the 'paired-down' early 80's models.
Porsche was trying to cost-reduce where they could during that time. Also notice the rear seat console is missing for same reason.

Nice 928!

 

This would explain it.
I think the seller is having a difficult time explaining what he is selling
Interesting that it still has P7's on it. They might get the car around the block once

 

That's odd, I've never seen one with those seats. The center console seems to have been redone also, I wish the dash had clear pictures.
