1. The 5 Mathematical Pillars of Car Valuation
Automotive pricing models analyze multiple historical data points to determine fair market value. The baseline begins with the original invoice price, followed by depreciation curves that vary dramatically across automotive brands.
- Age & Brand Depreciation Curve (Maruti/Toyota vs European luxury)

3. Regional Demand & Fuel Regulation Factors
In Delhi NCR, the 10-year NGT ban on diesel vehicles suppresses diesel resale values by 20–30%, while in hilly regions (Himachal, Uttarakhand) and southern states, high-ground-clearance diesel SUVs command premium values.
Used car valuations experience sharp drops right after crossing milestone numbers: 50,000 km, 75,000 km, and 1,00,000 km. Selling at 48,500 km fetches considerably more money than selling at 51,200 km!
