Just came back from a very warm and sunny Hockenheimring. Well, what can I say, it seems that many GT4s have been delivered recently. Within the many GT4s l was the only GTS. The owner's base seems to be very broad - one owner told me about all the improvments he already put into his car, with  GT3 cup parts and 200cells cat etc., etc, whereas another one was anxious that his GT4 may not be run in after 3000km on the speedo. I think that a lot of those guys actually replaced their potentially  envisaged GT3 with a GT4. Perhaps the GT4 has become something of a people's track  car and the GT3 is more  for the breed of motorsport professionals.
