Buying New vs. Buying Used: A Finance Calculator Comparison
The Quick Answer
Buying a used car typically results in a significantly lower monthly repayment and total loan cost due to the lower purchase price. However, a new car often comes with a full warranty and lower maintenance costs in the initial years. A finance calculator shows that on a R 400,000.00 new car vs. a R 250,000.00 used car, the monthly repayment can be over R 3,000.00 less for the used option, saving you more than R 100,000.00 in total interest.
Setting Up the Comparison: A Realistic Scenario
To make a fair comparison, let's look at two similar vehicles: a brand-new model and a 2-year-old version of the same car. We'll assume a 10% deposit, an 11.5% interest rate, and a 72-month loan term.
Scenario 1: The New Car
- Vehicle: 2025 Toyota Corross
- Purchase Price: R 400,000.00
- Deposit (10%): R 40,000.00
- Loan Amount: R 360,000.00
Scenario 2: The Used Car
- Vehicle: 2023 Toyota Corross (similar spec)
- Purchase Price: R 250,000.00
- Deposit (10%): R 25,000.00
- Loan Amount: R 225,000.00

Beyond the Calculator: Weighing the Pros and Cons
The calculator gives us the clear financial picture, but other factors are also important in your decision.
Advantages of Buying New
- Full Warranty and Peace of Mind: Typically includes a 5-7 year warranty and roadside assistance, minimising unexpected repair costs.
- Latest Safety and Tech Features: You get the most up-to-date technology and safety systems.
- Predictable Maintenance: You know the full service history from day one.
- That "New Car" Experience: The smell, the feel, and the pride of ownership.
Advantages of Buying Used
- Lower Depreciation: New cars lose about 20-30% of their value in the first two years. A used car has already undergone this steepest depreciation.
- Lower Insurance Premiums: The insured value is lower, which can lead to cheaper comprehensive insurance.
- More Car for Your Money: Your budget might allow for a higher-specification used model than you could afford new.
- Potential for Remaining Warranty: A 2-year-old car may still have 3-4 years of the original manufacturer's warranty remaining.
The Depreciation Factor: The Silent Cost
This is the single biggest financial advantage of buying used. If the new car depreciates by 25% in the first two years (R 100,000.00 on a R 400,000.00 car), that's a significant financial loss that you avoid by buying the same car at two years old for R 250,000.00.
Actionable Advice for Your Decision
- Prioritise Your Budget: If the monthly repayment is your primary concern, a used car is almost always the more affordable choice.
- Check the Used Car's History: Always get a comprehensive vehicle history report (like Dekra or TransUnion) to check for accidents or outstanding finance.
- Factor in Running Costs: While a used car has a lower repayment, budget for potentially higher maintenance costs once it's out of warranty.
- Consider a "Nearly New" Demo Model: This can be a great middle ground—significant savings off the new price, but with low mileage and a full warranty.
