997 GT3 (gen 1)
By the time the 996 GT3 gave way to the 997 GT3, Porsche understood exactly who its customers were and what they wanted to drive. So the first 997 was rip-snortingly quick, thanks to a Mezger engine by then up to 415bhp, and with some classy work on the aero front, actually quicker around the Nürburgring than even the previousgeneration GT2. So far so good, but it was also a very usable car, with decent ride quality and even reasonable refinement on a long drive. Better looking than the 996 and with all the improvements of the standard 997, to me this is the clear bargain of the Gt-series line-up.
