Dude, you could always just make up your mind and sell or trade some of your stash (cars, parts, hot wheels, etc.), stop paying rent on your multiple warehouses, or start charging admission and let all the geeks in to admire your collections.
With your profits you could pay someone to build a car to match your vision, not have to devote your time away from other interests and responsibilities, and truly have a one of a kind masterpiece. Done right on the right platform and that car could end up exceeding the value of the LE that doesn't get driven in order to keep the odometer under 10k. I say go silver before you turn silver.
Of course this advice comes from a guy who continues to buy stuff but moves slower than a snail when it comes to the actual build. I just really want to see the silver NA that I've seen photoshopped come to life.
