* Illuminated MKS sill plates – the "MK" is in white and the "S" is in red

* Unique exterior appointments, including EcoBoost badging, distinctive grille, front lip spoiler, rear fascia lower, side rockers and door cladding, decklid lip spoiler with chrome insert and modified MKS decklid badge ("S" in red)
ADDTIONS:
Mine does not currently have the decklid...hmmm - I think the Previous Owner banged up the trunk and just got a normal one and ditched the decklid spoiler. I knew it had some damage done upon buying (including myself when I rear ended someone just 5 weeks after owning it...damn soft brakes and ice)
* 20-inch chrome wheels
