Where can i go to buy a lamborghini?

my grandpa just passed away and me and my sister inherited a lot of money and i wanna get a lamborghini with some of the money but i have no idea how i would go about doing it!? theres no lamborghini places in my town and i highly doubt there would even be one in my state...
also how bad would the insurance be on one? my mom said she will help me pay for most of it on her policy or something but i still gotta help pay the rest of it which idk how much that is...
