So check this out...
I was tired of looking around for the access cover for my caddy. Found a few good prices from Cadillac parts companies. One was for around $50. Instead of jumping and picking one up I made one!

I went under the car and cut of a piece of the rear bumper. Now it may sound crazy but there is extra plastic that you would never ever notice missing. I cut out a 2X2 section out. I then taped a piece of white paper over the hole on the bumper. I took a pencil and etched the edges of the hole. I then cut the paper shape out. I took the piece of bumper and laid it over the paper and drew what needed to be trimmed. I took a grinder with a sand paper wheel and shaped the plastic to a perfect match. Cleaned the edges and glued it it place!
Perfect fit and no one would ever know.
Maybe I should sell a few?
By the way, "true story", no reason to lie, only reason to share a story with others that may have the same issue. There are actually people out there that think it's cool to steal parts off of others peeps rides!
