With reference to Nissan Sunny Diesel (with CD-17 or CD 20 engines), I have an understanding that its a great car with respect to performance, milage is excellent and and technology is better when comparing to corolla's 1C or 2C engines. I need your feedback and expert openion whether my understanding is right or wrong and secondly what about maintenance and spare parts availability in rwp and isb? would it be a wise decision to have one such car (preferably 97 to 2001 model Sunny 2.0D) in a very good condition and for which the price range also seems very attractive (considering that I have no issues in keeping and driving diesel vehicles)? what could be the potential issues and drawbacks? Your comments plz!
