General Motors Corp. is offering cut-rate financing for up to 72 months – including 0% on 36-month loans – on certain Chevrolet, Pontiac, Buick, GMC and Saturn vehicles.

The auto maker also is putting $1,000 cash on the hood of certain models, which can be combined with the lower-rate financing deals.

The discount programs begin Friday and continue through April 3.

GM, overall, has lowered incentive spending to raise residual prices on its vehicles, but is continuing what officials call “surgical” discount offers.

The spring event is the third such incentive from the auto maker this year and follows on what GM executives say was a disappointing February sales program that failed to boost retail deliveries enough.

The discounts extend to the Chevrolet Cobalt, HHR, Aveo, Malibu, Malibu Maxx, Equinox, Tahoe and Suburban; GMC Yukon and Yukon XL as well as Yukon Denali and Denali XL; Pontiac G5 and G6, GTO, Vibe, Torrent and Grand Prix; Buick Lucerne and LaCrosse; Saturn VUE, Ion and Aura.

Also included are the all-new GMT900-based Chevrolet Silverado and GMC Sierra fullsize pickups, as well as the outgoing '06-'07 GMT800-based Chevrolet and GMC half-ton extended-cab and heavy-duty pickups.
