It's not Brezza vs Urban Cruiser, but Toyota vs Maruti. and it's Toyota any day for service quality.

Last December 2020, I've bought Urban Cruiser Mid MT. I had very good experience buying from Toyota (I went to Maruti for Brezza, but didn't buy from Maruti only because of their behavior). I will definitely recommend Toyota as a brand. Riding quality and engine smoothness is there to be felt. Those skills are highly inspired by Toyota Fortuner. Urban Cruiser feels confident in high speeds. Mileage is decent for 1.5L engine. Servicing in Toyota is 5/5. They don't push you to buy unnecessary products unlike some other companies. And you get enough respect as a customer. As a con, no android auto in Mid MT, and no Hill hold assist. We expect these features after paying almost 10L on road price in Kolkata.
