Before I start, let me refer you to the Better Business Bureau page for HBL of Tysons: their BBB rating is an "F". Here is the link: http://dc-easternpa.bbb.org/codbrep.html?wlcl=y&id=172145008#Ratings
I placed a downpayment and 1st month payment on a lease. I was given the hard sell by Rosanne Baggett after first being insulted when I asked for a test drive. "It's Friday night, and I have someplace to be. I will only help you if you're prepared to buy tonight." Later, I apologized for "making" her take me for a test trive in the cold and she said, "what's done is done." Real nice.
However, I fell in love with the car despite her sour attitude. I told her I had an average credit score and she pulled it and learned that was indeed the case. I was told "you're approved, you're approved". I made a 4000 dollar downpayment plus a payment for the 1st month of 609.54 dollars. I signed the lease and they rushed me out the door on a Friday night, gave me the car without so much as even going over safety lights because "it had to be off their lot" (and Rosanne was cold).
THEN, midday on Monday, I was told they made a "mistake" and an addendum to the lease that I apparently signed permitted them to raise the lease from 609 to 779 dollars and I now owed them 179 more, plus 179 more per month. WHAT!?!!? So I told them I'd rather return the car. 7 days and dozens of insulting financing attempts later, including requesting an additional 16 thousand dollars up front!!!, I returned the car and they said they would credit my account the 4609.54 downpayment for a car I don't own and apparently never did. What legal right have they to keep my money, then?
In any case, the refund never came and I ended up losing $4,609.54 and have nothing to show for it! To sum up, I have no car AND no money. Its apparently a common (and illegal) scam called "shipping the vehicle." It is also one of the reasons the Better Business Bureau gave them an "F" rating.
That's right, an F. Finally, I contacted the Fairfax County Courthouse, where you can see 13 (THIRTEEN) similar cases brought against MB of Tysons in the last 36 months. I realize there are several positive reviews on this forum, but before you believe a word of them, check out the Fairfax County Consumer Advocate website and remember their rating of F from the BBB.... then head to one of the many other Benz dealers in the area.
As an aside, they offered me 10k on my trade-in while CarMax offered me 12.5k.
