AP V1 are not the easiest thing to sell since V2 has come out. I just sold my '06 STI AP V1 for $350 shipped and it sold in 2 days. I've seen others ask 375-500 shipped and sit for over 2 weeks. If you have time and are in no need to sell right away then start high but if you want it sold quick, $350 shipped for a V1 is a good offer. I sold mine on iwsti so good luck whatever forum you use and hopefully you get what you ask for it!
