I ended up picking this up in October. It's a 2007 GT500. I purchased it with 6,000 miles on it. Nothing really major since.  

I'm not sure that I would call myself an audiophile, yet. But I do enjoy the hobby. A coworker of mine showed me his pair of 555's. I gave it a listen for an afternoon and could not help but get myself a pair. I ended up doing research and exploring into an E-MU 0404 USB DAC for my computer...
