I'm thinking about buying a 2009 Porsche Carrera 2 3.8S (Gen 2 997). A good example with low miles seems to be selling for about £50,000. How would you rate this as a longer term investment (my thinking being it's a car that I love to drive but also the last of the hydraulic steering flat six cars)? Do you see prices dropping given the recent increase in Porsche 911 values? It may be a car I keep for 12 months or 12 years, so I'm just trying to get an informed opinion on likely fluctuations in price.
