The 6-wheeled Mercedes G-Wagon of Oleksandr Usyk is a Ukrainian modification of the factory Mercedes G55 AMG from 2007. That is, as TopGir already wrote, the world boxing champion did not purchase the original Mercedes-Benz G63 AMG 6×6 costing around 1 million euros, but bought a replica.

And it’s not that the copy is worse (and maybe not worse, or even better) than the original, but the media writes about a purchase with a price tag of 30,000,000 hryvnias. In fact, no, the cost of such a replica of a 6-wheeled G-Wagon in Ukraine is about 5,000,000 UAH.

Note, information about the modified G-Wagon follows from the database, which states that under the number KI0017TT was initially listed a 2007 G55 AMG.
