the windows u must get used to the differences.
the front, Mk II has a windscreen divider at the middle while Mk
III doesn't have. Mk II's radiator grilles and desto "black" area
are thinner and wider as well.
behind, Mk II has three depressed lines at the top while Mk III
does not have.
if in doubt, u can always see the rego. a 3-digit one is a Mk III
while a 4-digit one is a Mk II.
