Mercedes-Benz of Tysons Corner

I bought a new 2018 E400 coupe. The car was not detailed well at delivery, bad. The delivery was rushed The dealer did not bother to submit my paper work to my DMV - lied about doing it. Resulted in a ticket, fine and mark on my record. It is 2 months later and I have no tag. I called 4 times over 2 months and was told the paper work had been sent in and Maryland just is slow. As of today the dealer had not submitted the paper work. I got a hold on my record and a ticket for an expired temp tag. A long string of untruths.
