Do you remember MTV Cribs? Do you remember getting an inside tour of Shaq’s mansion? Well guess what: the dude still lives there! He bought it for about #3.9 million all the way back in 1993, and now it’s worth more than double that. The mansion may be one of the largest on this list, coming in at around 70,000 square feet, making it larger than some shopping malls. Of course, a lot of that square footage is devoted to the garage, which houses over 30 expensive performance automobiles.
