Thanks for this post, OP! I know this is a month old, but I'd love to hear from more folks that have accumulated a lot of miles, with and without performance mods. My commute is 40k miles per year, and the FiST is my DD. I've had my new '17 FiST for 35 days, and have just passed 3700 miles... I'm trying to decide whether to do any performance mods, or leave it stock and buy an extended warranty. The temptation to improve this already fantastic car is calling out to me, but I don't want to turn it into a money pit
