The 2011 Ford Fiesta is available with 1.9% financing this weekend.

Memorial Day weekend is historically when dealers promote sales and discounts. But with increased prices and limited inventory on fuel-efficient new cars and automakers spending less on incentives, shoppers will have to look a little harder to find the best deals this holiday weekend. Despite this, there are still interest-free financing deals, lease deals and cash back incentives being offered by several automakers.

Chevrolet is offering zero-percent financing on several of its cars, trucks and SUVs. The 2011 Chevrolet Silverado 1500 is available with interest-free financing for 60 months this weekend, or up to $4,000 in consumer cash. The 2011 Traverse is also zero-percent for five years or has $2,000 in consumer cash.

Ford shoppers can find low interest rates, zero-percent financing and cash back rebates on several models. Ford’s 2011 Fiesta, which gets 29/38 mpg city/highway, can be purchased with 1.9 percent financing for 36 months. Select Ford trucks and SUVs, like the Ranger and Escape, are available with zero-percent financing this weekend.

Nissan’s National Tent Event is going on this Memorial Day weekend, and shoppers can take advantage of $500 in holiday bonus cash on top of cash back offers up to $1,000 on the Altima, Maxima and Murano. This brings the Maxima’s total savings to $1,500, or almost 5 percent off the MSRP. The bonus cash is good through Tuesday. Vehicles like the Nissan Altima, Maxima, Murano, Xterra and Titan all are featured with interest-free financing this weekend.

Honda is offering weekend shoppers 0.9 percent financing on 14 different models for up to 60 months, or 36-month lease deals on five different models. Four of Honda’s five lease deals require $0 at signing for qualified shoppers. Honda is offering lease payments as low as $189 on its Civic Sedan this weekend.

These car deals expire May 31. No matter which dealerships you visit this Memorial Day weekend, keep in mind that you can negotiate the vehicle’s price beyond the advertised discount, especially since it’s the end of the month.
