Car depreciation explained: What affects your car’s worth?

Car depreciation explained: What affects your car’s worth?

If you’ve ever wondered why your car’s value seems to slip faster than a South African long weekend disappears, you’re not the only one. Every car depreciates, but how much, how fast, and why depend on a few key factors that every South African car owner should understand, especially if you’re eyeing the world of second-hand cars for sale or thinking about upgrading soon.

The good news? Knowing how your car ages helps you make smarter decisions about when to sell, where to find second-hand cars for sale, and how to get the best price possible.

Why cars lose value over time

Depreciation is simply your car losing value as the months and kilometres accumulate. But the rate isn’t random. Here’s what actually drives it:

1. Mileage matters (a lot)

  • The more you drive, the more wear and tear accumulates.
  • High-mileage cars often enter the second-hand cars for sale market at lower prices because buyers prefer fresher, low-mileage options (and even more so now with the petrol price drop).

2. Age + model perception

  • Some brands age like fine wine. Others… not so much.
  • Cars with a reputation for reliability hold their value longer. Those known for pricier repairs? Buyers tend to avoid them.

3. Condition is king

  • Even a 10-year-old car can fetch a great price if it’s well-maintained.
  • Service history, accident records, and cleanliness all influence value.

4. Market demand

  • South Africans love their bakkies and budget-friendly hatchbacks.
  • If your car fits a high-demand segment, you’re already on the winning side of depreciation.

How depreciation works in SA

While every car ages differently, here’s a rough guide to how values commonly drop:

  1. Year 1: 15–20%
  2. Years 2–3: Additional 10–15% per year
  3. Years 4–5: Depreciation slows slightly
  4. Year 6 onwards: Value stabilises at a lower, predictable rate

By year 10, the car has usually lost 70–80% of its original value. But here’s the twist: well-kept, fuel-efficient models can buck the trend.

Signs your car has held its value well

Even as your car ages, some green flags help you get a stronger selling price:

  • Full service history
  • Accident-free record
  • Lower-than-average mileage
  • Popular make and model in South Africa
  • Recent major maintenance done (tyres, cambelt, brakes)

These factors play a big role when you list your vehicle on a car selling website or browse second-hand cars for sale to compare values.

When should you sell your car?

Selling too early means you lose out on value you already paid for. Selling too late means buyers may see your car as a ticking maintenance time bomb.

A sweet spot often sits between years 3 and 6, where value retention and demand are well-balanced. If you’re selling a car privately, the timing becomes even more important since buyers are pickier.
