I believe that you are talking about Grant Ave?
I was just about to post that, the rest of the Grove is nice, there are some areas of Coconut Grove that rival ANY, in terms of rich people living there, the majority of the Grove is nice, its fun, there's the main tourist boulevard close by the water, beautiful.. but then there is Grand Avenue.. Don't EVER leave your window down, and avoid stopping at stop signs and traffic lights. Of course, those rules only apply for daytime driving, at night, DON'T DRIVE through there..
