Need advice regarding buying a car in my financial situation.

I am 25 and love cars and driving and am considering finally buying a sports car/sporty car to enjoy but need advice given my situation. I have zero debt and have been living below my means since I graduated college and working my butt off. Between my emergency fund, personal investments, and 401k I have about 160k net worth. I also have a paid off car worth about 15k if I traded it in. I do plan on going back to grad school in the next few years with an expected salary of 200k+ in that career. I would like to finally splurge and buy the car I’ve dreaming of owning for years. I would trade in my current car and pay the remaining 25-35k in cash. Should I treat myself or keep waiting until after grad school to finally start enjoying cars even though I feel like I could comfortably buy and maintain the car?
