1st maintenance at 10k km costed me 30k

First service costs whopping 30000, because you need to replace the break shoe after every 10000 kms and the cost it including GST is approx. 20000. If you have BMW, that won't give such heavy maintenance. At least BMW is big brand a luxury one you could pay that much for one service. I drive the car 10340 kms, I am a normal, carefull driver experienced driver for than 20 years. I have drive 90% in the city 10% out of station. AC filters get blocked always because of the dust in India. Truly it's not made for India
