Bro actual issue is demand and supply gap and due to long wait period there is always a RISK of increase in car price. So till the time Government cannot control this gap, OWN will be there in market.
I am not supporter of OWN money but I remember back in 2010 I bought Corolla GLI on 30k OWN. at the time it cost me 1454k inclusive of OWN and booking period at that time was 3 months. and after 2 days car price was increase to 1525k ( a 100K increase in Price). So if at that time i had booked the car on 3 months delivery, I had been end up paying 100K extra...
Now prices are increase insanely high and delivery timelines are stretched to 6 months and more in many cases so OWN money has gone high as well.
