2015 Dartz Prombron – at $1.25 million, the world's most expensive SUV

According to the top 10 list on this webpage, "Dartz Motorz Company is a privately held Latvian-based corporation that designs, manufactures and sells high performance armored vehicles... The 2015 Dartz Prombron is powered by a 180 hp Duramax V8 engine."

With a price tag like that it's clearly beyond the means of most school mothers; even the 10th, the 2014 Mercedes-Benz G63 AMG at $141,825 won't have a whole lot of potential customers.
