Actually just had it done last week at our tint shop. Went with 20% tint.
Just can't figure out where and how to upload a my own little gallery of pics...or how to add them to a reply like this one!
I'm planning on basic mods (Mostly cheap/free ones for now) Tinted glass, shaving the "Grand Marquis LS" badging off the back, and a simple thin chrome plate frame with the old hot-rod style bullet fasteners are all I've done so far. This week starts the stereo stuff!
