300C 3.0 CRD Experience Report Wanted

Hello, I’m thinking about buying a 300C Touring 3.0 CRD. But first I have to clarify some questions: -What is the consumption really? -What are the taxes? -What is the insurance? -Are the spare parts cheap? -How good is the quality? -Is the technology the same as with Mercedes? I’m grateful for any review (best of frequent drivers )
