I discovered that the price that the dealer was billing me throughout the transaction was much greater than the bike's retail price. When I questioned him about this contradiction, he got defensive and sought to ignore it. By then, I had already paid the amount, and the manager was unwilling to return it.
I looked into my suspicions online and discovered that I had been a victim of financial fraud. It appears like the vendor purposefully overcharged me for the bike so he could keep the extra cash for himself. I am appalled and disappointed to have been deceived in such a way.
