Hey Mauro, it's called 'value billing'. Mercedes charges us what we think we can afford, not based on their cost to produce (although that will be the 'floor '). As the car's value has risen, so has the 'value' of its parts. You can see that's how it works if you look at parts prices for, say, VW Beetles or Triumph Spitfires. I realized this when, some 20 years ago, a 300 SL crankshaft would cost $20,000 from Mercedes. Probably more now.
