This guy is right. I worked at Honda for years and the shipment of cars you received was very unpredictable. Maybe it's just Japanese automakers though. I also worked for a few GM dealers and they could tell you every last detail of what they were getting.
I do know that some Subaru dealers are able to track what they are getting...that's how I timed the purchase of mine. Only thing was I was tracking a SWP and a PBP showed up! Doh! Still love this color when it's clean.
Speaking of....could you give me an online appraisal of my 2012 WRX? This baby on the way has got me thinking of changing my priorities a bit. I checked your site out and you guys don't have a used car in stock that I'm looking for. Thanks!
