If you’re thinking...

If you’re thinking about buying a new car, read the figures below very carefully! They show the best and worst depreciating vehicles of 2007.

With the help of the vehicle valuation experts at Eurotax Glass’s Guide, we have compiled a list of the 10 motors sporting 07 or 56 registrations which shed the most pounds – and the least – in their first year.

To do it, Eurotax Glass’s has compared the list prices of all current models to their retail value now with 12,000 miles on the clock.

The worst of the bunch is the Proton Impian. Buyers would have paid around чЈ10,600 for the four-door saloon when new. But with a whopping 54 per cent depreciation, it is now worth less than чЈ5,000, according to the Glass’s estimates. The rest of the top 10 dropped an average 45 per cent in value – losing nearly half their value in only 12 months!

And there were some popular family models in the line-up. In joint second place was the Renault Espace. Alongside the Saab 9-5 saloon, the large MPV lost 45.5 per cent of its value, the figures revealed. In fact, the French firm featured no less than four times in the league table, with the Scenic and the Grand variants of both models also listed.

There were some surprising entries in our top 10 slowest depreciators, too. You would expect this list to be littered with supercars, where high demand always outstrips supply and ensures that values are relatively untouched. And true to form, the Ferrari F430 was worth exactly the same after one year’s ownership.

But Audi’s TT Coupé, which registered 8,091 sales in the UK last year, bucked that trend by coming second, ahead of marques such as Porsche and Lamborghini. The Volkswagen Eos coupé-cabrio did equally well in third, while MINI was a creditable eighth, ahead of Porsche’s 911.

Glass’s Guide chief car editor Jeff Patterson explained the VW’s success. “It hasn’t been on the used market for long, so values are still in their ‘honeymoon’ period,” he said.
