Many thanks Kezo but I think you mis understand what I’m trying to say I wish you lived closer I’d travel an hour to see you ! She said the n line loses 30 miles a full charge to the advance ! So with the advance I’d be gaining 120 miles a month so over 3 years that’s a lot of miles just wondered what cost we talking for these xtra miles ? Be as you said not much in it as heat pump improves the range I’ve just read . I didn’t know the power tailgate can be opened closed with key fob she showed me be handy at Tesco with my trolley ?
