the price quote you got was a total rip off... it would costs $250'ish for the front and $200'ish for the rear seats $600 at most.
i'd would just check your local classifieds / junk yard / ebay / craigslist.org and look for some 98+ leather seats, the seats are a almost the same but the newer version a bit better, the sitching is different. these run for about $250 more or less, and you can probably sell yours for $150 more or less.
authentic racing seats are expensive, especially Recaro. $500 more or less per seat.
