I am not sure I understand your question. Maserati of Naples has one trained mechanic who works on Maseratis. Two weeks ago they replaced the air conditioning compressor and other parts on my Gran Turismo (under warranty) in about 3.5 hours and seem to have done an excellent job. The only thing you should know is that they do all Maserati service in the Porsche workshop, the older building, as opposed to doing the work in the Aston/Bentley/Jaguar brand new building, which sucks! You have to go to the Porsche check-in which is not very nice. Why they did not use the new Aston check-in facility is beyond comprehension!
