The Toyota Prius and Lexus IS have shared top spot in a customer satisfaction survey carried out by What Car? and JD Power and Associates.
Owners of the Prius reportedly praised the model for its day-to-day operating costs, vehicle appeal and dealer service.
This is the first time that a hybrid car has been ranked highest in this particular poll, which was dominated this year by Japanese marques, with Toyota appearing twice in the top ten and Honda also performing well.
"The Prius clearly demonstrates that car owners think green is good," said Steve Fowler, editor of What Car? magazine.
"We know that there’s an increase in consumer interest in environmentally friendly cars here in the UK and with the Prius topping the model rankings in the 2007 study, we may be seeing a trend emerging in people’s thinking about these vehicles."
What Car? points out that Skoda also managed an "excellent showing" in this year’s survey, with the Octavia and the Fabia ranking fifth and seventh respectively.
One of the most improved brands of the past year was Mercedes-Benz, which was complimented for making "impressive strides" in vehicle quality and dealer service.
