The guitar that got away?

What's a guitar that you came across that you regret not buying?

For me it was a used 12 fret martin dreadnought, with mahogany back and sides. A store owner brought it in to a bluegrass jam and it was just a total cannon. I have a 12 fret martin with rosewood and its great, but I have to admit that one just had more punch. I've played other 12 fret martins, but that one really stands out.
