I've played a few and all were very fine sounding guitars. The necks are wide, but not overly thick. If you want a 12 fret Martin Dreadnaught, these are easy to like.

They're fairly scarce instruments, but that is true of most 12 fret Martins. Those who love them REALLY love them, but the crowd appeal is small. It was catalogued from 2013-2016.

The details....

Total production 181 Pre VTS and 27 VTS
2013-2014 Pre VTS and Thin Finish Package
2015-2016 VTS and Vintage Gloss Finish
Early 2013 production had fossil ivory nut and saddle, but was changed to bone later in the year.
They never had bone bridge pins. They shipped with solid plastic pins and slotted bridges, but pins were soft plastic. Entirely unsatisfactory IMO. I would immediately change to Antique Acoustic pins, as I did with my D-28A 1937. StewMac pins are nice too.
