The smartest and most financially sound way to own a car is to never buy one new, always pay cash, and get one used that's about 5 or 6 years old. After the 5 year mark vehicles tend to get much cheaper and have had a lot of their depreciation. I don't take this advice because I enjoy cars and am a car enthusiast. The advice is true non the less.
I have found though that most of the time, though very frustrating, when people ask for advice they don't really want advice or sound reasoning. They want someone else to tell them what they want to hear so that they can rationalize and justify what they already had their mind made up to do anyway.
I am not upset, you haven't lost anything unless you sell it. I will continue to drive and enjoy it. Mine has USS and Brembo brakes in the rear + the AMD Ryzen and HEPA. Does one need anything else?
