if you booked on 27 june then FED is already applied on the price, the tax now stands at 2.5% plus 17% making a total of 19.5% for this car

This is the price that i have booked my car at on 24th June so i dont understand how come your dealer is asking for anything more?? or have bought a car on the own money and new invoice of those vehicle is more so more of the tax stuff??
