Nah, I don't think he has money like that. Not to long ago, he was on Celebrity Big Brother. A place where faded or Z listed celebrities go for an opportunity at some clout.
When you Google his networth, the sites that list him as being worth 300 million aren't reputable. It honestly reminds me of that Lorenzo Von Matterhorn shyt Barney pulled off
I'm sure that he has a decent chunk of cash due to the attention he has generated for himself and his supporters, but I'm not seeing how that generates enough for him to have a fleet of expensive sports cars. You'd expect him to be like a Messi or a Ronaldo, when he is actually tapping into a niche part of the market.
My estimate would be under $5,000,000.
