Any good dealers in the new orleans area? Chevy

So I decided to take a look at the volt since they have the 7500 federal rebate and all. Apparenly on a lease atleast locally there are no incentives according to my dealer. They cant even come close to the 299 lease special advertised even with less miles.

$521 after tax for 36/10k which I know is crazy. Thats even after the dealer takes off 3000 of dealer discount.

49% residual and MF conversion was 1.66%. Anybody can throw me any ideas on this one? They were telling me that tax was going to be alot more than just $30 on the 299 lease (9.75 here) and that theres a ton of fees and all kinds of other stuff.
