Based on similar cars' selling prices it would still fetch close to $1K when I'd consider selling it. If I do. It all depends when 2015 or newer Honda Fits come into the sub 5K price range.

And then again later on I may decide my car looks too ugly and want to restore it to stock.

For certain values of 'modifying the car' YES. You're trying to modify the preformance envelope without modifying the engineering.

However if you allow removing the trunk lid, tail lights and back bumper and storing them in a clean, dry place then the story changes...

Bolt the outer corners of the box cavity to the sockets for the tail light housings and run flying buttresses to the roof, like a Ford GT40. And what XKCD/37 would call a big *ss-diffuser:

Makes sense, although I kinda thought the air settled back down over the rear roofline and then created drag after the rear.

VERY helpful, and much appreciated!! Something I will definitely keep in mind if I can come up with a way to make it attach without drilling and yet be sturdy enough, and also be cost effective enough since coroplast would block the line of vision.
