The Formula
Cost/Mile = Base Rate × Age Multiplier. Base rates: Compact 8%, Sedan 12%, SUV 15%, Luxury 20%.
Why It Matters
Your 7-year-old luxury sedan at 15,000 miles/year will cost ~$2,800/year in maintenance. After 10 years, that rises to ~$3,500/year. Budgeting $250/month prevents being caught off guard by a $2,000 timing belt job.
