You very likely can take advantage of the new offer. Your best chance of doing that, though, is to work transparently with your dealer. You want a cheaper car, sooner. He wants to sell a car sooner. This is a win-win. Why go to other dealers and bring potential conflict into it, that will just give your dealer a reason to be difficult about returning your deposit.
