Real Example: Total Cost Calculator in Action
Here's how the Total Cost Calculator revealed surprising results for one reader:
The Scenario
Comparing a £15,000 used Sedan vs. a £18,000 used SUV
Quick assumption: "The SUV costs £3000 more"
The Calculator Results (5-year ownership)
- Sedan Total Cost: £28,450 (£5,690/year)
- SUV Total Cost: £35,200 (£7,040/year)
- Real Difference: £6,750 more for the SUV over 5 years
The difference wasn't just £3,000 - it was fuel costs, insurance, maintenance, and depreciation that made the real gap £6,750!
