I did trade the car for $5k towards the non-Pcar. It is interesting that I had coolant loss issues for two years prior. No one (dealer or two independents) could detect coolant in the oil. The dealer replaced the coolant tank. I heard rumblings about casting porosity in early 996s (mine was one of the first 500 off the line) I finally just added about 250ml of coolant each month. There were no other issues until a cold January day (-5 F) when bad noises came from the engine on startup.
