Porsche 911 Carrera Cabriolet

The Porsche 911 Carrera Cabriolet is the slowest car in the United Kingdom. Not because of a lack of performance – far from it – but because vehicle valuation experts CAP predict it will lose value slower than any other new model over the next three years. On this basis, an example registered new in mid-2012 is likely to have a “future trade value” of 55.3% of its original price by mid-2015. This assume it has covered a mileage of around thirty-thousand.

This raises a fascinating question... why such slow depreciation? There are a number of factors to consider. The first, of course, is supply versus demand. The Porsche 911 Carrera Cabriolet has only been on the market since December 2011 in its present form. That ensures a limited second-hand supply. Coupled with fair/high demand, this is guaranteed to affect values.

Secondly, a new 911 from mid-2015 is likely to be very similar to this year's car. No new model, in other words. On this basis second-hand examples should still look bang up to date. In contrast, one of the best ways to devalue a car is to launch a successor.

The Porsche Boxster is likely to depreciate slowly too. It is therefore predicted to retain 51.9% of its value over the next three years. Again... this is a recently introduced model so second-hand supply is limited. And again... it should look fresh in 2015 as any replacement will be on the drawing board. Perhaps we should all forget the banks and invest in Porsche.
