Are CLK electronics centralized?

[Robert Cox]

I'm currently considering purchasing a 1998-2002 CLK cabriolet. However, I'm somewhat reluctant due to the number of electronics problems these cars seem to exhibit eg. unexplained stalling, windows not closing fully, seats not sliding forward, mirrors not tilting back radio/CD failure etc.(and even MB extended warranties appear to have limitations on fixing electronics problems).

Talking to CLK owners, these can often be minor problems that sometimes fix themselves or can be "reset" by removing the battery for a few minutes.

Does anyone know if the electronic gadgetry on cars like the CLKs are all under the control of a single "module" like the ECM, or are there a multitude of electronics "black boxes" scattered throughout the bodies of these cars??

Thanks.
