## Beyond the Factory Warranty

New Cadillacs come with a factory warranty (typically bumper-to-bumper for 3 years/36,000 miles). An **extended service contract** kicks in after factory coverage ends, protecting you from costly repairs on powertrain, suspension, and other major systems.

## What's Covered?

Extended plans vary. Most cover:
- Engine and transmission
- Suspension and steering
- Electrical components
- Air conditioning

They typically *don't* cover wear items (brakes, wipers, tires) or routine maintenance.

## Length and Cost

Plans range from 5-10 years and 50,000-100,000+ miles. Price depends on your vehicle, plan length, and deductible. Our Finance team can show you options.

## The Value Angle

If you plan to keep your Cadillac beyond 5-6 years, extended coverage can save thousands on unexpected repairs. If you trade or sell earlier, some plans transfer (ask specifics).
