I say go for it. Ultimately, can you find a better deal with patience? Possibly, but this one is the color you want, in like new condition, great service records in it's short life, ZERO rust, and honestly IMHO the price is respectable and in line with the current market. It sounds like a really nice find and I don't see anything (from what you've said) that would scare me about this deal. The CPO is retroactive from the initial purchase date which is why purchasing the '15 over a '13-'14 is advantageous. You essentially still have a 5 year/100k mile powertrain, and the remainder of the factory warranty. Good luck either way...I know it's not a cheap decision. Ultimately, I don't think you will regret it
