Good vehicle but hopeless service backup and no spares for repairs

this is to bring to ur notice that I am one of those unfortunate owners of Fiat Siena TD 60 .Though the machine is good when compared to other cars the service of Fiat Dealers is absolutely hopeless They are bothered only to rob the money from the vehicle owners and least interested in good servicing and maintaining good relations
Another point is the non availability of Spare Parts .We had to wait for 2 months to get one Strut Assembly and another could not be secured and I had to put one which is not supplied by the Company
I had to face problems and humiliation from the Dealer and Service Incharge everytime I went there
I have decided to give an advertisement in the Local News Paper against the new Fiat vehicles to be launched
I have set apart 40,000 Rs for this purpose and I feel that nobody should purchase a Fiat vehicle in future
