2003 Lincoln LS
The 2003 Lincoln LS is a mid-size luxury sedan that offered a blend of comfort and performance. It came with two engine options: a 3.0L DOHC V6 producing 232 horsepower and 220 lb-ft of torque, and a 3.9L DOHC V8 generating 280 horsepower and 286 lb-ft of torque. Both engines were initially paired with a 5-speed automatic transmission, though later models offered a Getrag 5-speed manual transmission with the V6. Owners appreciated the LS for its stylish design, comfortable ride, and European-inspired handling. Common complaints often centered around electrical issues, complex electronic systems that could be prone to failure, and the relatively high cost of repairs due to the car’s luxury nature.
