So I bought my first car a VW Golf
Model Variant GOLF
Model Description 1.6 TDI 105 S 5dr
Year Of Manufacture 2013
Registration Date 02/12/2013
I would like to know what Mark Golf it is, is it mk6 or mk7
The year of manufacture denotes which "Mk" it is.
EDIT: After some further digging, I realized the Mk6 & 7 were a little strange in that those in North America spanned different years then those in Europe.
As for a tell tale between the two, you need only to look at the hood (bonnet). The Mk6's hood has a rounded and smooth line from the A-pillar to the front, where as the Mk7's hood has a sharp line.
So, that would mean my first guess was wrong on your Golf as it is a Mk7. Strange world we live in.
