You are getting lots of excellent advice here. I hope you're writing this down.

Personally, all kidding aside, I would probably spend around $4500-5K on an Orbea or a Trek with each's super-cool custom paint job of your choice, then, go to Mallorca and France/Italy/Spain for two weeks. The memories you create from your trip with your ridiculous bike will be worth way, way more than $7500.
