Yeah , unfortunately a main dealer on an island.
I tried to buy a EQ fortwo a few years ago when Smart were taken reservations , they took a large deposit then told me three months later they weren’t allowed to sell Smart EV’s , I then got an ex demo ED forfour from a smart dealer in Norfolk - top notch service.
Last year we had the ED serviced here and they left my missus on a saturday afternoon with 5 miles range left in the battery , i asked for a battery print out for the traction battery and they gave us a slip of paper for a 12V battery test , even worse they changed the brake fluid on a car with 2000 miles and left so much air in the system when i got back to the UK i had to bleed the brake system because the car was undriveable, unstopable 
Back when the first left hand drive smart for twos came out UK spec we had problems with the electric windows , air bag and a service. All botched by this dealer.
Only three spark plugs changed because they didn’t know about the other 3 on the back of the engine, they gave my missus a can of wd40 because that needs to be sprayed down the window guides everytime you open and close the electric windows and the famous air bag light.
Four times it went in before they fixed it , on the third visit they said they changed the air bag. Before the visit we used a UV pen on the airbag and wrote something rude , after the airbag was changed and we have the invoice the words were still on the airbag. They brought the wrong colour so they just reset the fault code and lie to us.
Need less to say the next service and airbag change was all done for free 
Legendary bad garage and they are main dealer for a lot of cars now.
I plan to get the Smart serviced on the mainland next time i visit.
This experience just shows how bad and dangerous they are and now batteries are involved
