Owning exotic cars ain't cheap -- just ask Floyd Mayweather who spends more on an OIL CHANGE than some people make in a year!!!!
TMZ Sports spoke with Floyd's longtime car guy Obi Okeke -- aka Dr. Bugatti -- who was on his way over to oversee maintenance on one of the boxer's "triple red" 2012 Bugatti Grand Sport Convertible.
Okeke has previously told us the car is worth around $3.3 MILLION.
So, how much does an oil change and a tire replacement run on one of these supercars?
