AUBURN HILLS, Mich. -

Chrysler said Wednesday that it is extending its Minivan Month promotion as well as its RamBox and no-charge HEMI engine promotions through the end of May, while also revealing a few new incentives for the month.

Back in April, Chrysler had revived its 60-day “Minivan Pledge” to kick off Minivan Month. The pledge — which lets purchasers of 2011 Chrysler Town & Country or Dodge Grand Caravan models bring back their ride within 60 days — has been extended through the end of May.

Other deals associated with Minivan Month are as follows:

—Buyers of the 2011 Town & Country can receive either $750 Consumer Cash or as low as 2.9 percent financing for 60 months (for qualified buyers). These buyers are also given $750 in Bonus Cash.

—Those buying the 2011 Grand Caravan can either receive Consumer Cash of $2,000 or go with financing as low as zero-percent for 60 months (assuming the customer qualifies) for most models. They also can get as much as $1,500 in trade-in support.
