I wasn't the only person who offered $40 and another guy said maybe $50 was the top price to pay..... but LOL. a year later and you still haven't sold them. They are used floor mats, not aluminum heads. Keep holding out for that extra $10 my friend. My offer still stands. If not, I'll bet you in a year they have another inch of dust on them from sitting on your shelf.
Good luck with the sale....
