A couple of DGT questions?

[ruger9]

I'm looking to buy a DGT this year, but it'll have to be used. Sometimes sellers don't list a couple of things (and maybe don't even know), so...

What year did the V12 start? (I read they are going back to Nitro for 2019... will ALL the 2019's be Nitro?)

What year did the updated coil split wiring start?

Nevermind, stumbled across a thread elsewhere, looks like V12 was announced fall of 2010, in production 2011-

Updated coil splits 2012-
