Yeah, ok, I'll be honest: I don't quite get the post. It just sounds like bragging. I get the car love; I have a StupidCar myself, which is quite ridiculous and deserves to get me booted from this forum. I justified it similarly to the way you did: I am FI; we have chosen not to RE for several more years; I have wanted this specific car for close to 30 years; I found an ok deal on a lightly-used one with almost all of the features I wanted;* and I do not regret it one bit and adore driving it and put the top down whenever the weather allows** because it makes me happy.
But I also don't post about it much here, except in situations such as this to show that I "get" the car love, or to illustrate my own lack of mustachianism. Because, I'm sorry, a StupidCar is not remotely mustachian. On the "knee of the curve" scale, there is no way this thing is even close -- I paid close to 3x what I paid for my prior car, and I am not getting 3x the fun. And, you know, that's ok -- we all have our "things," and if this is yours, more power to you. God knows that mine is worth it to me. I also don't feel like I have to justify my decision to anyone, because it was a personal decision, and I am happy with it, and anyone else who would like to run my life for me can go fuck themselves; I'm not aspiring to be a "perfect" mustachian or a "perfect" anything.
But there's a big difference between "don't have to justify" and "flaunting." My decision to buy the car is not something I feel like I should be bragging about here, on a forum dedicated to encouraging less consumption and more environmentalism. It is anti-Mustachian, completely contrary to the ethos of the blog and the forum, and not something I expect folks here to pat me on the back over.
There are very legitimate and issues in the post that merit serious discussion -- e.g., the value of being a SWAMI instead of going full-FIRE; the value of EVs; the concept of how you decide for yourself when to be frugal and when it is worth it to stray; how much is "enough"; etc. It's just hard for me to engage on those substantive issues when the post seems to focus on "I just dropped almost $200K on fancy cars and it was the best thing I've ever done!"
So sorry -- it just rubs me the wrong way. I come here to be reminded that I don't need my StupidCar to be happy. I get enough people telling me I "need" stuff like that to be happy in my real life.
*There are only a few hundred of this particular make/model/trim level made any year, and I wanted one of three years, so the perfect car probably doesn't even exist.
**By "allows," I mean "is above 40 and not actively raining."
