Hi,, Both automatic and manual transmission versions of the Honda Civic model are equally suitable for the Indian road conditions. Also it depends on your preference of transmission that suits your driving style more. If you are keen on high fuel economy, then manual transmission is a better option. However, if hassle free drive in heavy traffic condition is what you are looking for, automatic transmission is the option you should go for. Thanks,
Honda recently discontinued the Civic in India, however you can buy a used Civic. You can visit our, used car section, where you can find good deals- http://www.cardekho.com/used-honda-civic+cars
Well, it is quite early to reach on any conclusion, whether the service network you visited provided you the correct information or not. We would suggest you to search for another service station, if it also gives you the similar advice then it would be better to repair your car. Their could be multiple reasons behind the noise coming out from your car's engine such as badly aligned camshift belt, faulty front brakes pad, and not so proper felt belt.
