OSLO (Reuters) – On the outskirts of Oslo, a row of Fiat 500es imported from California stand parked in the snow outside the Buddy Electric dealership, part of a global flow of pre-owned electric cars to Norway powered by green subsidies elsewhere in the world.

A gleaming blue Fiat 500e is on sale for 129,000 Norwegian crowns ($15,000) with 24,000 km (15,000 miles) on the clock. It costs about 20,000 crowns($2,300) to import and adapt each Fiat, Hanssen said. On U.S. used car websites, similar Fiats in California are advertised for about $10,000. Norway has the world’s highest rate of electric car ownership in the world, partly thanks to long-term perks such as free or discounted road tolls, parking and charging points, which boost the appeal of second hand models unwanted elsewhere. The government also exempts electric vehicles from taxes on traditional vehicles that are very high in a country which does not have its own fossil fuel car industry to lobby against them. Rebates offered by other countries are another part of the equation. In California, residents who own a new battery electric car for at least 30 months can get a rebate of up to $4,500, said John Swanton, of the California Air Resources Board. The Fiats show how varying incentives around the world to promote electric cars, spurred by efforts to combat climate change and limit air pollution, can affect trade flows. They can also distort national goals for shifting from fossil fuels, although U.S. exports to Norway of 4,232 used electric cars in the past two years are tiny compared with U.S. sales. The state of California alone aims to have five million zero-emission vehicles on its roads by 2030. The issue has a bigger impact in some European countries, which may be over-estimating the greenness of their domestic car fleets due to exports to Norway, where top plug-in cars include Nissan Leafs, Volkswagens
