Hi Ellie. To my knowledge, those bumpers are US spec (and probably a few other non UK countries). Whilst it's right hand drive I checked the DVLA MOT history checker and entered your registration number to see if it might have come into the UK from another country at a later date and, well, see the attached screen shot. I've never had this come up before, did you HPI/ history check the car before you purchased it?
