I have a 3000 CC Safari Dicor 2006 model. I am pretty satisfied with the car. It is very Spacious, Sterdy and comfortable car. Till date I never had an issue with the car. However tatas service network is pathetic. Its better to get your car serviced outside then at the authorized dealer.
Also dont take extended warranty. It covers nothing at all. At the time of selling car the dealer promises you that everything which is covered in warranty is covered in extended warranty also but in realty it is totally opposite. Main aim of selling extended warranty is to ensure that you get your car serviced from authorized dealer for 4 years instead of 1.5 years(or warranty period).
