Upon aquisition take it to your most trusted luthier and have the bracing scalloped. Any Martins after 1968 had to have thicker bracing to maintain the 'lifetime' warranty. Then when CS&N hit the QC situation worsened. One would be MUCH better off finding a Gurian of that vintage...late 60s early 70s. Much better guitar for about the same money. I owned two of them and would stack them against any Martin I've ever owned or played. Very underrated and overlooked guitars.

That being said 2000.00-2500.00US is a fair price for a '69 Martin D-18 in decent condition.
