4K is relatively acceptable.
My dealership quoted me 22K for registration at the time of booking, so I would effectively end up paying 3K as commission while taking delivery in October, but dealership asked me to forcibly get tracker, costing 20K, installed from them, which meant dealership would earn their remaining commission from the tracker itself to extend their total commission from 3K to maybe 7K.
I didn't debate with them much, since they were the only dealership, which accepted Alto VXL AGS booking at that moment, and I was also in dire need of a car.
These dealerships know very well how to mint cash from public using one way or another, irony!!
