I have one, it’s a great guitar. The fretboard is made from a composite on ones made in the last few years, although you would be hard pressed to tell it’s not wood. I love mine, I had a Taylor 410 prior to the D16-GT, and although the Taylor was a more expensive guitar, I much prefer the ‘woodier’ sound of the Martin.
Martin’s tend to come with a fairly high action from the factory, so you may find you need a setup if you like a lower action (the previous owner may have done this).
I can’t think of a better guitar for a first quality acoustic, but different people prefer different things.
