THE MG6 has been named the worst value car, losing 75 per cent of its value in three years.
The Chinese motor fell from £18,600 when bought new to £4,600.
Second worst for depreciation was the Fiat Qubo, which goes from £15,794 to £4,720.
The trendy £22,135 Fiat 500L dropped to £7,375, according to Auto Express.
Falls are based on them clocking up 36,000 miles over three years.
The worst ten includes British favourites the Vauxhall Meriva (£19,007 to £6,392), Vauxhall Cascada (£28,326 to £9,887) and Ford Ka (£9,790 to £3,550).
The cars are often priced too high, said the magazine.
And by the time they are sold they may no longer be fashionable or have suffered from negative publicity.
Luxury cars often lose more but because they are so expensive, the actual percentage loss is less.
The exception is the £69,000 Maserati Quattroporte, which will drop £45,000 in value to £24,000.
Auto Express, which used predictions from used car experts CAP, said: “These depreciation disasters can be good news for used buyers, but for the original owner, they’re a costly headache.”
