Welcome to Fear City.

Amid spiking crime and violent carjackings involving luxury vehicles in NYC — like last month’s “great first date” turned action movie, complete with guns shoved in the face of a $150,000 BMW-driving Romeo — well- heeled Gothamites worried about getting to the Hamptons this summer are clamoring for their own exclusive, secure “supercars.”

Among the most sought-after armored automobile suppliers is a former Austrian commando who helps give billionaires peace of mind by fortifying their homes, helicopters, superyachts and Range Rovers — to the tune of millions of dollars.

“People need to understand one simple fact: they need protection,” Matthias Fitzthum, CEO of Bespoke Home & Yacht Security, told The Post of the souped-up security measures he says any “ultra-high net worth” family would be crazy not to follow. “An alarm system isn’t protection — they need hardware to protect their family and themselves.”
