1. Its the cumulative service cost (of both service together) during paid service.
> Been Honda Labor charges for paid service including GST would be like eating up 50% (as Rs 2000 + 18% GST in every service)
> Engine Oil & OIl Filter need to be replaced every 6 month which what cost Rs 1500 (including GST in every service)
and are other components as per recommended service schedule
2. Indeed, Brezza will end up to be more fuel efficient
City 4th gen mileage in local usage would be like 11 to 12 KMpl (on highway with cruise at speed of 90 kmph can get in 16 to 17 kmpl_
But Brezza can expect to be 13 to 13.5 Kmpl in simiular condition while on highway can touch in 18 to 19 Kmpl even
3. For Nexon
a) Ingress, egress is not as ease as in Brezza or Wagon R or XUV300 even. Floor placed at height and senior member may face slight issue. to give a demo pls check this video at 13 minute 42 second onwards
b) Not as fuel efficient due to heavier kerb weight
c) Cabin do not feel as well insulated as like Brezza or City
Hope should help !!
