Hello, would like to buy me a SLK R170 from before 2000. What do you generally think is a better purchase to buy the SLK 200 or the SLK 200 compressor? I heard that the SLK 200 is a lot cheaper in the insurance than the compressor. And I think I heard that the SLK 200 without the compressor also consumes less gasoline.. Would like to hear your opinion. MFG Andreas
