if you can i'd take it to a mechanic to see why the car failed emmissions. i know my car didn't pass emmissions because the tester just couldn't connect with my ecu. i had new cats and everything still failed. but yea, who knows it could have failed because the owner did some kinda modifications to it or something. i mean 24k, that car could still be under the factory bumper to bumper warranty and u might be able to take advantage of that.
