Mercedes-Benz of Chantilly

Zubed Chowdhury was a well mannered & courteous sales rep to deal with. Excellent sales person.. Finance Manager was good too. Very soft spoken & polite. However, I have one question that could not be answered that could not be answered by your team members. On my purchase of GLC300 last week I was charged taxes which were neither explained to me nor were explained/deciphered on sales order. When I went back & asked reason for that I was told it is Louden county(LC) tax (0.17%). Unfortunately, I could not get an answer/explanation for 1. Why LC tax was levied on my purchase when to my knowledge dealership location & my purchase is in Chantilly. 2. Even if it is to be charged then why it is not shown clearly/explicitly on sales order? I am sure your team members must be doing what they have been trained/told to do but this ambiguity in customer dealing leaves a bad taste after good experience with sales person. I certainly expect an explanation for it & i am open to update if I am missing anything. If my observation is correct then it should be rectified ASAP & I should be compensated suitably. I hope someone out there reads it & acts/responds.
