Generally, you shouldn't make permanent modifications to a leased car. The vehicle must be returned in original condition (normal wear and tear excepted), so custom wheels, paint, or major upgrades could result in charges at lease end. You *can* add temporary, removable items like seat covers or floor mats. If you want to personalize your Cadillac, buying might be the better path. **Before making any changes to your leased vehicle**, check your lease agreement or call (779) 265-4427 to confirm what's allowed. Our team can clarify the rules and help you keep your lease costs down.
