Hello Kezo I’m just back from my dealer in my village she has told me the n line loses 30 miles to the advance now then im not good at maths but I charge it once a week so that’s 120 miles a month what is that in 3 years ? I have saw the black n line hybrid same as electric but grill different ! And saw the black advance which I’m going out in the morning ! If I order tomorrow I can tell you more but many people are watching this regards ordering etc sorry to be a pain asking you a maths question many thanks once again
