There is a black set on eBay right now for a very high price - $ 8500. They have been on there for many months but the seller is holding with that price. Robb
You should consider a set of US F40 seats or 348 SS seats. They're carbon fiber backed and bolt right in and they're lighter than the 355 sport seats. I have a spare set in black leather and I hope will bolt right into my 550 Maranello.
I know of a set in Europe for 10,000 euro that were offered to me Not sure they are still available. I will check Too rich for my blood
stock black seats plus $4k you pay shipping.i've been given 6k just for the seats but i need stock seats in return.
