I purchased a new Martin acoustic from Mars Music in late 2002 as they were closing their doors for good. In fact, I believe I may have been their very last customer at that location. I got a great deal on the guitar but I never registered it with Martin. Recently, the binding began coming loose and I contacted a local authorized Martin repair shop. They said it should be covered under warranty and they advised me to call Martin to register the purchase. So I called Martin with every expectation that they'd laugh at me but to my surprise they were eager to help. Bottom line, Martin allowed me to register the purchase 18 years later and they authorized the warranty repair. As an aside, since Mars went bankrupt, there's a decent chance that Mars never even paid Martin for the guitar in the first place. Thank you Martin Warranty Department.
