1
Electrical Systemmoderate~60,000-100,000 mi

2
Body & Chassis Rustmajor~Any mileage (age-dependent) mi

Like many vehicles of its era, the Regal is highly susceptible to rust. Critical areas include rocker panels, wheel arches, floor pans, subframes, and around windshield/rear window seals, especially in regions with heavy road salt usage.

3
Automatic Transmission (4T60)major~90,000-150,000 mi

While generally durable, the 4T60 automatic transmission can develop hard shifts, slipping, or fluid leaks due to aging seals, solenoids, or lack of fluid changes. Torque converter lock-up issues are also noted.

90,000

Maintenance & Assessment Zone

120,000+

High Risk & Restoration Zone
