It's been two years since OP has asked and he never replied after asking. I've checked BMW i8 and I don't think someone who has the same reference as OP will choose it.

It's a luxury car and only a few can ride. I get the idea of OP when he has asked about choosing between a truck or SUV. He is unlikely to choose this type but I would love to have it someday when I don't have to think of expenses and I have a lot of spare money to buy it.
