Even if you get the dealer’s info, what makes you think you will be able to get the same deal? FWIW, most dealers might not have much stock of the Plus trim. Even if they do, they are probably not going to offer 12% off MSRP just because someone on this forum got that deal. Most deals posted by other members have been around 9 to 10% off MSRP.
If you need a car this month, I would strongly recommend working with one of the broker’s in the Marketplace.
