Boston University also has a high percentage of international students who are very wealthy. The cars they drive are Lamborghinis, masseratis, land rovers along with high end Mercedes, bmws and Audis. It has been this way since at least the 90s. They buy cars and real estate in cash. A story from 2015 said that intl students spent $120M in Greater Boston not including tuition. I would say BU students are the most visible of that wealth. There was a recent news alert about Intl BU students being scammed out of large amounts of money.
