Why These Tasks Matter
Depreciation hits hardest in the first 5 years. New vehicles lose $4,334 per year on average (Source: AAA 2025 Your Driving Costs study). Neglect leads to bigger drops. Clean records and low mileage keep buyers interested.
Many drivers skip small jobs. This causes issues like worn brakes or low oil. Result? Repairs spike costs to $965 monthly ownership average (Source: AAA 2025 study). Stay ahead to protect your investment.
