Even in the second decade of the 21st century, it's not uncommon to see an old $5,000 Honda Civic outfitted with more than $5,000 in "performance" modifications: massive spoiler, low-profile tires on 20-inch rims, high-flow exhaust system, etc.

It's much less common to see a $50,000+ car outfitted in a cloak of invisibility, so it's probably worth taking note when one drives by.
