The Mercedes-Benz Executive Choice Fleet Program is offering a $5,000 incentive (an additional $3,000 combined with the current fleet incentive of $2,000) on the 2005 S-Class (S430 and S500). The offer includes 4MATIC all-wheel drive at a no-charge option and applies only to company-owned vehicles and those purchased or leased by executives with company allowances. The incentive is valid on vehicles in stock or ordered from September 1 through December 31. Additionally, the new executive allowance bonus enables executives with individual automobile allowances to take advantage of the same fleet incentives available for company-owned or leased vehicles. The executive allowance is deducted from the transaction price at time of purchase. The S430 features a 275-horsepower 4.3L V-8 engine, while the S500 is powered by a 302-horsepower, 5.0L, V-8 engine. Both models feature 4MATIC all-wheel drive, Airmatic air suspension system with adaptive damping, DVD-based GPS navigation, the Tele Aid telematics system, leather upholstery, wood trim, 12-speaker Boss sound system with digital surround sound, and the electronic stability program (ESP).
