The place is in this area called "Gross Point." LOL, I wonder how "Gross" Gross Point is. However, for business I have to drive Downtown also for the day and will be parking there, so I wont be in the Gross area, only overnight.
Grosse Pointe proper is, as was said, arguably one of the areas where the most well-heeled residents of Michigan live. Having said that, it does border Detroit and there will be some blending of good and bad at the borders. If you're in a sketchy area, which would be near the North and Northwest borders, you'll probably know it.
Grosse Pointe is outlined on this map. It encompasses only one square mile.

Just go with your gut feeling and you and your car will be fine. The perils of Detroit are overblown to a great degree. But that doesn't mean one should let their guard down. You'll be fine.
The following is just for informational purposes: In the heyday of the auto industry, the auto execs lived in Grosse Pointe. They built their large homes there, (some are mansions) so that they could be near their place of work. Grosse Pointe borders the Detroit River so they had access to that also. A lot of things influenced the downfall of Detroit. The Grosse Pointe area was impacted by that downfall. You can't have a ritzy area in the middle of a city that is experiencing squalor on a large scale and not have it be affected. Downtown Detroit and the Pointe's (Grosse Pointe and Grosse Pointe Farms) are by in large safe places to be.
