AITA for buying a Tesla?

Idk if this should be in a different reddit. Anyways, I'm a mid 30s guy, I had 20k in savings, I work in mobile app development and freelance on the side- and needed a new car. For clarity- I live with my brother, it saves us both money and we live rurally for cheap.also due to the political climate recently me and my family vote red, so please, let's not even get into that, that ain't the issue and I don't want to make this about Elon or whatever's going on.

Anyways

, I consulted him about buying a new (used) car, going over my wants I told him I REALLY want a Tesla, I'm a hugeee tech nerd and the whole family knows it (I'm the tech support of the family)- it should be a no brainer that Tesla would be my preferred choice. Anyways, when I told my brother- he made a big DONT buy a Tesla statement, as if it was the worst choice in the world. He wants me to get whatever's cheapest and works and he considers Teslas to be over the top ultra luxury with zero real world value. He's also a car mechanic and is partial to Hondas and yotas. Anyway, I figured, I'm a grown man I'll buy whatever car I want. It's my money after all. Anyways so I found an "entry level" 2019 model 3 for only 11k. I paid cash and somehow haggled the deal to 10k firm. No one in my family knew I was buying it - they only knew I went to get a car. Anyways, I was so excited- I love my car. I was in a state of giddyness and proudness. I drove to my parents house, my siblings were there and everyone wanted to see what car I got! I pull up and you can immediately tell they were disapproving and upset. I was trying to show them all the cool features but they couldn't care less. My dad then goes "great job, now you'll be able to drive and look fancy while ur doing it" in a sarcastic tone. Now I'm a humble guy, Im not rich, and I buy everything second hand and live as cheap as I can. I HATE showing off- they begged to see my new car! I thought it would be a happy achievement cuz I was upgrading from a 300k mile truck I drove til it's last breath. I work VERY hard to save my money, and the car was 10k$ with less than 124k miles on it!!! My dad's car was 26$k new and he's judging me on my purchase when he'll be making car payments for the next 7 years or so?!?!? It really soured my mood and made me feel like I'm trying to be "boojee" or something. I could care less about how I look, I love Teslas High tech features and modern-ness!! But they see me as trying to be "fancy". The only one who was even happy for me was my baby sister and me and her drove around town and it cheered me up a bit. Fighting the urge to re-sell it now :( any advice? I don't care what strangers think about me, but I do care about how my family perceives me. ;( they make me feel like I just made the worst financial/car decision ever. They did the same thing when I bought my truck because it was a piece of shit in their opinion.
