The depressed value of sterling has provided a windfall profit opportunity for those classic car owners who have been prepared to sell their cars to overseas buyers, according to Glass's Guide.

Sellers of good-condition, left-hand-drive cars have found that the European market, which has long paid higher prices for such vehicles, offered a great return on investments made prior to 2008, when the value of the euro was just under €1.50 to the pound. Now close to parity with sterling, the euro is so strong as to offer Europeans a great chance to make a killing on a classic, and it could equally benefit Britons looking to sell their cars.

John Glynn, older car editor at Glass's, explains: "A car purchased in Europe three years ago for €22,000, and sold today at the same price it was bought for, would bring in £20,000 - a tidy profit for the vendor of £5,200 after three years. Cars that might benefit from such a scenario could include anything from a 1980 Ferrari 308 GTB to an early 1990s BMW M3 Cabriolet (E30 model).

"With many classic car values having risen by around six per cent year-on-year since 2007, profits might be even higher. The same €22,000 car could now be worth about €26,000 or £23,800, which would equate to a £9,000 return on investment."

Richard Jackson, who three years ago collected his 1982 Porsche 911 Turbo from Switzerland, has just sold his classic to a European buyer. The increase across the two transactions equated to almost €11,000, with the weakened pound pocketing Mr Jackson a profit of just over £10,000.

It's not just private owners who are reaping the rewards of high demand from the euro-zone. Dealers too are reporting strong sales of most left-hand-drive cars. Many deals are done before cars have even entered showrooms, and some long-standing stock is catching the eyes of buyers in Europe and the US.

Glynn adds: "Classic cars are a great investment tool, if you know the market and you enjoy cars. The exchange-rate effect means the UK may lose some lovely machinery this year, which will sadden some enthusiasts but it cannot be avoided. Of course, it also means there will be an appetite among successful sellers to acquire replacement models, which will stimulate the UK market once again."
