Yes, dropping a VW-V6 engine on the Cayenne is a big mistake, I don't know what they were thinking either.
I'm more pissed than you about the RMS issue Ben, but lets keep things in perspective, its just a small leak that neither compromises the safety of the occupants nor is it a risk to the engine (you can drive around with a RMS leak and when you come around to it you take into the shop), its just a monetary issue, normal Ferrari scheduled maintenances set you back further than replacing an RMS leak in the 996 (if out of warranty) or the blowing-up M3 engines are a real issue. You mention the 993 but the 993 had worse issues including the wiring harness which was even a safety issue, and there are other issues more expensive than the RMS in the 993. But the RMS leak is hardly enough to call the 996 or 986 junk, "junk" is the posture Porsche is taking on the RMS issue, thats what makes us really mad, but not the issue itself nor the car is junk.
