2018 BUICK REGAL SPORTBACK

0% APR for 72 months for qualified buyers on most models*

Plus, receive $1,500 down payment assistance when you finance through GM Financial*

*Must finance through GM Financial. Not available with leases and some other offers. Take delivery by 4/2/18. See dealer for details.

This is for the Sportback only, which I assume includes the GS. Does not include the TourX which is being offered with 0% for 36 months.
