I went through the same thing, I decided to save the 10% and get 2020 that isn’t my perfect spec. In hindsight, I think this was the right move because a bunch of things I really thought I wanted/needed wasn’t a big deal. Now that I’ve been driving a few months, I’m planning out my perfect GTS spec!
How did you get the first picture with the aftermarket rims? I think a light coloured car should have dark wheels. And if you aren’t going with MissionE, just keep the calipers in Red and save the money.
