I'm happy to report that "post-purchase money-pit creep" need not apply to this particular problem! There are various clever solutions to be found on the internet ranging from water bottle holders intended for bicycles to a very nice 3-D printed bracket.
I stumbled across my own solution right after I parked Serena in the garage for the first time, using the cheapest of cheap coat hooks leftover from a project I never started in the house we'd just moved away from. That's right, kiddies, my procrastination had saved me a cool 100 cents. Plus tax. I think the setup is pretty elegant in its simplicity and ease of use... and you can't hardly beat the price! Frankly, the only thing more impressive than the price is the availability (any hardware store) and the ease of installation (under 5 minutes).
Amazon. They're so cheap no one else bothers to sell them through the internet. Not even from Hong Kong! Best I can figure is that inflation has pushed the price up to about $4 for a 2-pack of similar hooks. Every store has them or something similar, trust me.
Are you more visually oriented, like me? Check out the video version of this post that I made to show off how cluttered my garage is:
