I sold my soul (well, a Simon and Patrick and a Washburn) recently for a Martin SPD16, and I love it too. My 1968 D18 is still with me, but enjoying a bit of retirement.Like women and small daughters, guitars appreciate being loved and played with.
My 4x4 is a little more sybaritic - a Subaru Impreza Sport, but that won't still be around in 50 years.
