Summit has the black ones for $279 each. I found a place seems of have all the colors, but it's an import parts site. If you don't mind buying from them, the site is
here.
The maroon vinyl ones are $279 each. That's where I think I'll be getting mine. I know they're pricey, and I could just get new covers from Brett for $309, but then I would have new covers on my uncomfortable seats that don't recline. Hmmm...
