I also have a set of seats from a 2005 WRX. All are black and in excellent condition. Nyspeed discount price of $350 firm. Parts are in West Seneca.
Link to my ebay ad:
I know it’s a tough sell. But I’d be interested in the fronts only if you get no interest.
Id be willing possibly to sell only fronts. Rears go online, and easier to ship.
