EDIT May 4/09: voting is open, here: VOTE! April 2009 Modification of the Month
---
I'll start the ball rolling by nominating skyl4rk's
Nissan Versa Base 1.6L
This ongoing project started out with some discreet & nicely made grille blocks, and some data collection to document the MPG improvement seen.
... And then
WHAM! Out of left field we find a prototype coroplast removable boat tail under construction!
(Hopefully my nomination isn't the kiss of death, skyl4rk - I don't have a bad track record that way.)
Anyone else seen any good projects/tests/threads this month?
Don't forget, active projects that were previously nominated, but didn't take the crown in previous months are eligible for re-nomination.
