Search constantly, search everywhere and wait until it's your turn to get lucky, 18 months ago was vastly different than today too. There is no magic to a deal, just persistence and waiting for the right one to come along. Any other gen 2 isn't hard to find for OK prices stillI'll give you $18.
...but in all seriousness if you got a blue/white GTS for under $60k that's a damn steal. Shoot me a PM on how you found it, or any shopping recommendations.
