Good car. Needs refinement. Engine noise like a truck after servicin. service stn says thats normal

Most of my comments would be as I mentioned in the Pros and cons. Indigo was TATAs best effort. I like it. Its fuel efficient and I do not expect it to be refined etc.. what bothers me is the noise from the engine or clutch and service station OMR checkpoint chennai says its normal.. the problem started after I gave the vehicle for a clutch replacement there.. Poor pickup with or without AC.. but seriously overall its a good vehicle..Tata can do better am sure.. or is it that TATA can do well only in its Car shows?Good fuel economy, good value for money, boot space, good designcheapo plastic dashboard, poor finishing in all aspects, service stn: OMR checkpoint chennai
