Sad to see the Master Cylinder has failed, Slave cylinder was usual problematic, hope this doesn't start happening in other cars. Did you talk to anybody else in Concorde, apart from Khan? It is always good to talk to some seniors in case you are not getting satisfactory answers. Though Khan is good chap, but talking to Ratish might have expedited this. Good that Fiat responded appropriately. You could have seen the difference RSA makes. They send a flat bed big truck, and takes cars on it, not towing it. Do update KHT service thread, this is not acceptable from KHT with whom we have high hopes.
