What year is your m3, and is it manual?I am having the same issue. I want to get a GTR and sell my 2018 BMW M3. But the prices are crazy. They want $104k for a 2016 stock and even more if the see it has wheels, bigger spoiler. So not sure if i should wait till the market equalizes or what... I hear that a FBO on GTR will get you like 640? I am at around that with my tuned M3. so would it even matter, does it drive that much better than an M3?
