Ended up selling the car this weekend to a friend for 15,000 (who's going in eyes wide open on cars past experiences, etc.). Sad to see it go, but moving on to the next chapter (which will likely be an SUV of some sort).
With the Miata in the garage, I just couldn't justify having manual transmissions for both cars I own when the fiance can't drive stick, and one needed to go. As much fun as I've had with the GTI, it was an easy decision for me given the trackability of the Miata (RWD, LSD, light weight, etc.), It's lower miles, and the fun factor. It's been a hell of a ride with this car and I have zero regrets.
Thank you all for the support, advice, and community over the years. I'll continue to follow the forum and I hope to bump into you at the track in 2021. Be safe and have fun!
