Which high-performance sports car should I buy?

I am a pensioner and have a budget of around £50,000 to treat myself to a 'fun' car before I am finally too old to enjoy driving. I have owned many high-performance cars in the past and I shall keep my Audi A3 3.2 Quattro for everyday use. My shortlist, all of which I have driven and would purchase from a main dealer with an appropriate used car warranty, comprises: Bentley Continental GT, Audi R8 V8 Coupe (manual) or the Porsche Cayman S (PDK or manual), but not the newly announced model. My annual mileage in the car would not exceed 4000. What do you think?

The Audi R8 V8 manual if the money stretches to it, but they can be quite high maintenance. An RS4 certainly is. Or the new model manual Porsche Boxster S that has much better ride quality than the previous Boxster. For a fun car, a convertible makes more sense. And a Boxster has two boots, front and back, so is a better tourer than the new Jaguar F-Type that doesn’t have a lot of luggage space.
