According to EurotaxGlass’s, two and three-year old examples of best-selling superminis, such as the Ford Fiesta and Peugeot 206 equipped with low-capacity diesel engines, have seen their price premiums increase from around £200 last year up to £500 now.
“Diesel vehicles generally cost more new than comparable petrols, so it would be expected that they are worth more on the second-hand market,” said Jeff Paterson, chief car editor at EurotaxGlass’s.
“However, the heightened level of demand for small diesels witnessed this year has widened the price gap over comparable petrol models.
"Other running cost benefits are attracting drivers to small diesels. In particular, changes to passenger vehicle tax bands have focused the minds of consumers on the need to consider CO2 emissions when buying a car, with many diesels now bettering their petrol siblings by qualifying for a £35 per year tax disc.”
“The trend is more striking in urban areas. The possibility of the London congestion charge being waived for vehicles which fall into the ‘sub-120g/km’ category of CO2 emissions is a further reason for buyers in the south east to choose a modern diesel supermini over a petrol one.”.
