WITH Britain basking in a heatwave it is perfect weather for open top driving and experts at HPI have come up with their best buys for the summer.

The HPI team crunched the numbers to find the top 10 list of least depreciating convertibles and came up with the models which are not only ideal for enjoying the sunshine but could also prove to be savvy purchase.

Best in class is the Porsche 911 (991) Cabriolet which although priced in the region of £96,000 at new, will retain on average 59 per cent of this value over three years and 60,000 miles.

This is closely followed by the Porsche Boxster, which costs almost half less to buy - £50,000 from new but retains 56 per cent of its average new price and the Range Rover Evoque Convertible which holds 53 per cent of its original value.

At £13,000 less to buy than the Evoque, the Lotus Elise S2, one of the lowest price cars in the top 10 at £36,000 will retain 53 per cent of its average new price.

The Top 10 best convertibles currently available according to HPI are the Porsche 911 Cabriolet, Porsche Boxster, Range Rover Evoque Convertible, Lotus Elise, BMW Alpina 4 Series Convertible, Lotus Exige Roadster, Alfa Romeo 4C Spider, Aston Martin DB9 Volante, Mazda MX-5 and the Audi TT Roadster.

HPI’s Clive Wilson said:  “When the weather is as glorious as it is as the moment there’s nothing better than being able to enjoy life on the open road with the top down.

"Our list of best depreciators has identified some superb vehicles that will retain their value well over a three year period and possibly beyond, so a great purchase for those with the money to splash out and derive maximum enjoyment without having to worry too much about the car losing its value.

"However, summertime is far from the ideal season to pick up a convertible as this is obviously the time of year when they are at a premium but for owners looking to sell on to those with the money to spare it can be very good news."
