Chryslerís Letís Refuel America $2.99 Gas Guarantee Plus Cash program has been extended through July 31. The program continues to help improve showroom traffic and drive sales of the companyís most fuel-efficient vehicles. For July, the program will offer the unique opportunity for customers to lock in their gas prices at $2.99 for three years and get cash back (on the majority of vehicles). The other two incentive choices offered are cash back alone or 0 percent APR financing. Since the program began in May, the vehicles in Chryslerís lineup with the highest gas program take rate were the Chrysler Sebring Sedan, Dodge Journey, Dodge Caliber and Dodge Avenger.
