20k is a smoking deal for a forced induction low mile car. Don't let the cheapskates hammer you down, if you offered it for 15, they'd want it for 10. Stick to you guns, it's worth every dime.
How much for the passenger mat including shipping to TX?
I wholeheartedly concur with your post. Those who are interested in buying this car and understand its value will not be influenced by the mindless noise of the minions.
