8. French Firepower
Former US Marine Gregory Marshall combined his love for the American military and French culture by fitting his Citron 2CV with an 88-millimeter cannon. The classic compact car, known for whizzing through the streets of Paris, received a deadly upgrade, making it a unique military vehicle. With a blend of US Marine-inspired livery and an attachment that allows the car to be driven on train tracks, Gregory’s car train hybrid turns heads as it blasts through the French countryside. A true testament to DIY military ingenuity.
