It cannot be stopped and neither the goverment can stop it.
Premium pricing is a phenomenon practiced worldwide and in every industry.
It's all about demand and supply.
You came in the line early, got something earlier and want to sell it at a Premium, and the buyer wants to purchase it at a premium. It's simple give and take
Companies like Suzuki, Toyota, Honda rely on invertors to give them guaranteed sales. They give them priority deliveries.
The wrong practice is that usually bookings are closed for a random walkin / Cash customers while these investors and banks can go in any time get a car booked and delivered on priority.
But own/Premium this would never end.
Even Disney land has Premium pricing if you want to break the line and go earlier then the rest.
Passport office mei bank slip bhee bikti hai, if you want to skip the line.
If today everyone starts booking cars in the system and stop buying on premium in 3 months time everything will be shattered.
A week ago I called a honda dealership for a honda city.
"He openly told me readily avalible nae hai ap 80,000 own dedein company se nikal wadeinge"
That too open invoice, and was open for offers. Since 80k was only demand.
