V8 guzzler..! Sorry sara3 too expensive to run & when you get to my age-it's also toooooo noisy! ;) I just want peace & quiet.....even when I'm driving ;)
The Tesla company claim the car should get 100.000 mls life from theirs AND it does the equivilant of 225mls per gal. to petrol. Cost = 3cts per gal......All sounds pretty efficient to me, but I'm not an expert.
