997 GT3 RS 4.0
Until the 911R came out last year, this was the first Gt-series 911 to be built to a strictly limited number. Just 600 were constructed and, if you weren’t a favoured Porsche customer, you didn’t stand a chance of getting one. Using the crankshaft from the RSR race car to raise its capacity to 4 litres, it had the torque the ‘standard’ GT3 RS lacked, making it an easier yet more rewarding car to drive. Few come to market and all fetch huge money; even so, if you ever fancied tying up some cash in a Porsche, this would appear a gilt-edged way of doing it.
