Aw heck, follow your heart. We only live once, and, well, consider carefully, imagine riding that 30,000th mile and if you're smiling or not, then decide.
Boys, and many men after them, revel in the building, and quickly tire of the having.
How many of us have an abode with less room than it might otherwise have, for our accumulated toys, and how much do we hear our mate complain ? All items that tickled our fancy at one time or another, and sit idle now.
So maybe build the bike, for the joy of it, and sell it to make room (joy having been had) -- when that 2020 Rocket shows up.
