Ive done my full car service at RNS Motors Kodigahalli branch. Next day of the service car broke down after just driving 200 KM.
When I talked at RNS Motors about this, got reply that carbon clearing in engine is not part of their service. Im not sure why that is not part of the service if they know old car can broke down.
RNS motors just wanted to make money by doing service with new vehicle, they dont care of old cars. Also they dont care of the customer what they suffer because of car broke down in night at lonely highway.
Ill suggest people can do service in private but do not do car service in RNS Motors.
