Electricity cost for my Imiev is about $25/month for my commute. The same commute in my C30 would be more than four time as much just for gas. The Imiev has needed no repairs in the six years since new, and maintenance consisted of checking tire pressures, topping up the windshield washer fluid and occasionally replacing wipers and cabin air filter. The Volvo is a year older, but in that time it's needed oil changes, brakes, shocks and struts, a timing belt, a/c compressor, and a front suspension rebuild. Maybe the Volvo is driven twice as much because of weekend trips, but operating costs are hugely more expensive. The Volvo has much better heat in the winter however.
