Congratulations on your purchase, unfortunately I havent been able to get hold of a center arm rest. Lack of cupholders in this model has been very irritating for me and I havent found any other solution apart from holding a bottle of water between my legs -.-
Since the EF civic and our City share a lot of interior panels, maybe an EF arm rest may fit although that's a rare find as well.
You can have a look at my car in person anytime soon, hit me up whenever
