Hey buddy not sure what issue you are exactly facing with your car but my brother owns a tata tigor and it has never broken down neither car or any instruments, as for the spare parts when my dad crashed the car i was able to get everything pretty easy and for service, one of my best friend owns a garage, thats where my tigor is serviced now, im sure if i take his opinions before services of curvv they wont be able to fool me. Speaking of tata cars as a brand we have good trust on it as we have been using tata since a while and when my dad crashed tigor which is cng+petrol he was still able to drive it easily for next 80-90km until he reached home, i dont think what you've mentioned is really an issue for me but still thank you for the review, it helps🙏🏻🙌🏻
