I would personally be ok with it if it is not warped. I would get a magnifying glass and look all over it for any signs of micro-cracks starting and if you can't see any, it should be ok. I don't know where you are physically, but you could probably do better with the price. I would imagine shipping is a big part of the seller's asking price. If you can find a local seller, it would be better as you can inspect it on-site, avoid the shipping cost, and maybe gain some confidence in the car it came from.
