Hi all, just had someone reverse into my car, very minor damage to washer cover, merc dealer has said because of slight buckle, I'll need a complete new front bumper, not an issue as chap who reversed is willing to pay, but ideally I'd like the bumper from the facelift 2010 year as it has the lower led running lights. My car is 2009 plate cl500 with Amg body kit, does anyone know if the 2010 will fit ? I know merc will instantly say no, wondered if anyone has done it.....

Thanks, mark
