So AM Works officially offers the conversion to proper manual transmission, seems to be a nice OEM job, with freebie upgraded dashboard and console too.
I've seen a converted manual Vanquish for sale a while ago, a TS member (from the ME, I think?) mentioned it ... there are some articles on the net but that's about it!

Has anyone seen it for real? Driven? What about NA cars, no US authorized shops?

Gratuitous Vanquish shot ...
