Premium aside, you've got to decide what it's worth to you. Any color/stripe combo with that low milage is going to command a few more dollars.
Get the VIN checked, ask all the questions, drive it. Take a five day break then go back and buy it. Wait, that's how I did it.
You decide if the extra bucks are justifiable. Once it's in your garage, no one will know (or care) how much (or how little) you paid.
If oportunites like this present themselves to you often, don't sweat it. Another low mile, beautiful blue&white will come along eventualy, right?
