27k-Mile 2005 Cadillac STS AWD

This 2005 Cadillac STS is an all-wheel-drive example that was configured with the 1SG Premium Luxury Performance Package at a cost of more than $13k. The 1SG Package provides the 4.6-liter V8 with Performance Cooling equipment, and it also affords 18″ aluminum wheels, 17″ disc brakes, Magnetic Ride Control, and Intellibeam HID headlights. Inside the cabin, the Package offers Eucalyptus wood trim, navigation, a Bose surround-sound system, Premium Tuscany leather upholstery, front-seat ventilation, and heating for the front seats, rear seats, and steering wheel. The battery and tire-pressure sensors were replaced and paint correction was performed under current ownership. Finished in White Diamond Tricoat Metallic over Light Gray, the car spent its first 21 years with a single registered owner, and it now has 27k miles. This all-wheel-drive STS is offered at no reserve with a window sticker, the owner’s manual, service records, a clean Carfax report, and a clean Connecticut title in the seller’s name.

Finished in White Diamond Tricoat Metallic (98), the car was equipped with HID headlights with Intellibeam and washers as well as a sunroof, a rear spoiler, and Rainsense windshield wipers as part of the 1SG Package. A paint chip on the right front door has been touched up, and work in May 2026 involved correcting the paint and applying ceramic coating.

The 18″ nine-spoke alloy wheels were refinished under current ownership and are mounted with Evoluxx Capricorn UHP tires that show production date codes from 2024. 17″ disc brakes and Magnetic Ride Control are included with the 1SG Package. The front brakes were serviced in early 2026, per the seller, who also notes ceramic coating has been applied to the wheels. The tire pressure monitor sensors were reportedly replaced in April 2026.

The 1SG Package equips the cabin with heated and ventilated front seats with power lumbar support that are upholstered in Light Gray Tuscany leather, which extends to the heated rear bench. Additional package features include Eucalyptus wood trim, navigation, and an in-dash CD changer linked to a Bose 5.1 Surround Sound system. The cabin air filter was reportedly replaced under current ownership.

The heated wood-trimmed steering wheel is mounted to a telescoping column and frames a 160-mph speedometer, an 8k-rpm tachometer, and auxiliary gauges for coolant temperature and fuel level. The digital odometer indicates 27k miles.

The 4.6-liter Northstar V8 features a Performance Cooling Package as part of the 1SG Package and was factory rated at 320 horsepower and 315 lb-ft of torque. The battery and air filter were replaced following the seller’s acquisition of the car.

Power is sent to all four wheels through a five-speed automatic transmission and an all-wheel-drive system.

The window sticker lists initial delivery to Schaller Cadillac of New Britain, Connecticut, along with standard equipment, options, and a total vehicle price of $64,730.

The Carfax report is free of accidents or other damage.
