Hi guys, i am a 996 c4s owner and needs some questions answered.. how do you access the service information on the centre screen (no service info on 996's) do 997s have obc (computer) as standard. I think all facelift 996s do.. how much is a 997 cab 05 plate with nav, multifuntion steering wheel, bose, heated seats, memory seats, electric seats, 6 cd player, phone module, auto dimming mirrors, manual, 25k worth?? A friend of mine has one but it is a C2 as opposed to a C2s... but it does have a high spec... needs the 4 year service also!! Not sure what to do?? Any suggestions.. what do u think its worth?
