Is acquiring $110,000 as a newly 18 year old a lot, and what are some general wise investments with this?

I'd like to blunt about this. This money is being inherited from my stepdad who I rarely see (so I haven't gotten too much useful financial advice). Along with this, starting at age 18, I'll be making roughly $1,000 a month for as long as I can through a family owned website that I prefer to keep anonymous.

So I'm Matt, I'm 17, and turning 18 in early August, as well as attending university shortly after, and I'm completely lost on how to spend or make proper use of this money. I've honestly never acquired anywhere near this amount, and I'm afraid I'll spend it all unwisely on clothes and bad stuff. This money isn't being used for my college tuition, but only on a car that I'll probably spend around 40k on in August. Other than that, I have little logical plans with the remaining roughly $70k, and my monthly 1k income. Even at university, I am willing and planning to work part-time at any job to bring in more money during the school year.

I just want some opinions on what I should be doing with this money/income, and how I can invest this to something good for myself financially in the long run, rather than wasting it. What would you do in this situation? What are some wise investments, or general advice? Or where *could* I find helpful financial advice if anything?

Any advice and comments are welcomed and thank you.
