Hah dont worry, my adult brain has this conversation every single day. Dont waste your money, invest more of it into shares, pay down the mortgage. Then the bedtime insta doom scrolling begins and after being bombarded with gtr's my mind is set: im definitely getting one!
I have the current model mx5 as the weekender, but i just miss my boost and literally like your username, the sututu's that come with it. I remember with my 2nd supra, as it had twins and vvti, they used to spool real early, like 1,500rpm so you could just be a spooly boy all day long. Some people say they get over it after a while, not me tho.
