It does extend well past the 2003 models... even the new 997's have the issue.
If the RMS goes, you've probably have a bigger problem with the engine. The bearings (design flaw) are going, causing the crank to make the seal more "oval".
Since I had the RMS done at the first sign of oil leak, I assume the motor would eventually go pop.....
The Turbo cars are much better. They are based on the old air-cooled motors, and don't seem to have this problem.
I'd never want to own a Turbo car, but in this case, a Porsche 911 Turbo would have been a better choice.
