oh i'd say they might be worth $50? - as i'm after a set!! quite honestly it goes on condition - i have no idea what factory aus lights are worth from a wrecker - i'd say about that sort of price. (worthless if you have them for sale, worth whatever someone is prepared to pay for them if they really want them)
mint airvent is worth $50 maybe (i got a damaged one for nix). i know someone after one in any condition for their racecar too by the way)
