Financial Responsibility

So I’m 20 years old, I make about 120k a year and have no debt besides my car. I had bought a 2018 Shelby GT350 and loved it until it was totaled. Now that it is totaled, it has me wondering upon my financial responsibilities and how to better myself. I started my credit journey at 18 and now have 3 credit cards, and my auto loan with perfect credit history putting me in a good position. My question is, I’m a big car guy and want to buy another cool car, but am I better off buying something cheaper and investing my money into rental homes since I will have 2 years of work and credit in January (which is what my real estate agent told me I need in order to buy my own home), or will buying this car not affect that.
