So I have a 2018 WRX and have someone who has a 2015 STI who will do a trunk swap, he has the wing trunk and I have the lip spoiler trunk. And both WR Blue. My car is just over 2 weeks old so perfect condition and his is a 2015 so few years older. What is a fair cash price to add on top of the trade. And this is in Canada also so price will be diferent. He thinks 250 is to low, based on the 2 trunks is that a fair price or is one of us out for lunch.
