Welcome Along
Having moved from the UK to Canada, you will find the roads scarily small compared to the US, especially the B-roads but that being said . . . I think the UK roads are way more fun for a car like the Zed
The only thing to think about would be the steering wheel being on the wrong side, mainly from a overtaking, accessing car parks point of view . .. . and since you are American . . . . drive through's
You could probably sell it for more in the US, taking in to account the shipping costs and EU conversion required (lights etc) you can get a decent one when you get there for less money . . you never know might stretch to a 370
