Still new Corksport Aluminum Undertray/Skid Plate, compatible with 2014-2018 Mazda 3.
Direct replacement for the plastic undertray, with an access panel for oil changes.

For now, it'll be just local only until find a box or good means of shipping it.
(I can also deliver to the Denver or even up til the Grand Junction area even, as visit the two a fair amount).
and set to email notify, so should be available while listing up.
