I never understood this thing. So next time a guy knocks on your car window while you are waiting for a green light in Avenida Reforma, what are you going to do? Tell him to inspect the SELs and bezel insert numerals to demonstrate it's a ZZF v2 instead of a $10,000 Rolex Submariner?
Hand the rep over and be grateful it wasn’t a £10k gen?
Go home, Pick up the phone to VSF and get another one shipped over.
