Only person who is going to know you spent $100k is you and the few car fanatics.
Example: most people don't know the price difference between a 3 series BMW and a 7 series. The look similiar from a glance. But the difference in prices is immense. 35k to near 100k. I see 100 silver mercedes every day and I don't give them a second look.
I think if you are going to spend 100k on a car it should be instantly obvious you are ballin or at least trying to look like it =P
