It's at the discretion of the manufacturer as special financing offers are manufacturer incentives offered directly to the consumer. Mazda may give additional monthly, quarterly, or year-end incentives to dealers, which is not typically disclosed to the public. This allows the dealers to mark down vehicles at their discretion. That's why some dealers are able to mark down more or less depending on how sales are going for them in a particular month.
That being said, Mazda may come out with another financing offer and/or cash incentive -- although the latter is unlikely for a '17 model while 16.5s are still readily available on dealers lots -- or extend the 0%/36 through the end of August and come out with new Labor Day offer at the last minute like they did with July 4th.
If you're not in a hurry to purchase, I would wait until at least end of Aug. If you're itching, start emailing dealers now as we're approaching the end of July and a dealer may make a special offer to hit their numbers for the month to get a bonus. I started emailing dealers in May and didn't purchase until July during the July 4th financing special (0% up to 63 months, 90-days deferred payment).
Of course, if you're financing through your own bank or CU, this is all moot. I would hold out until later in the year for a '17 and a cash rebate. Just my 2-cents.
