The 500e is going on sale imminently in the UK (the new version). Not sure what colour/location brake lights and indicators the US 500e has, or what fog lights/reflectors it has. The modifications to make it compliant could be costly. I can't recall if the 500e has rapid charging, but if it's CCS Type 1 you will not be able to rapid charge anywhere (we use CCS Type 2). Also while the Type 1 inlet will accept 230v, will it be happy at 50hz rather than 60? I'd hope so but not sure.
