What happens to the pre-order amount I paid?

What happens to the pre-order amount which was paid? Does that get refunded during full payment?

The pre-order amount gets adjusted against the full payment amount. For instance:

Assume the cost of the vehicle during you purchase is, 1,20,000 and you had paid 5,000 as the pre-order amount. Now, for the final payment you will have to pay a total of 1,15,000 for the purchase of the vehicle, the pre-order amount gets adjusted in the final payment.
