Should I Fix a High-Mileage Car or Trade It In? A Practical South Africa Guide

Overview: should I fix a high-mileage car or trade it in?

Owners of high-mileage cars often face the same question: invest in repairs or trade the vehicle in and move on? The answer depends on repair cost versus retained value, safety and reliability needs, future running costs, and the specific market for parts and salvage in South Africa. This guide helps you assess both paths and gives local examples for Johannesburg, Cape Town and Durban.

Key factors to weigh

• Estimated repair cost (including parts and labour) in R
• Current private-sale or trade-in market value of the car
• Likelihood of further faults given mileage and service history
• Urgency to replace the car and cash-flow considerations
• Availability of a fair way to sell the vehicle as-is (e.g., to a specialist buyer)

Repair cost vs value retained (example table)

Figures are illustrative and approximate for South Africa in 2025; local labour rates and parts costs vary by city and model. Always get multiple repair estimates.

When repairing makes sense

• The vehicle has a full service history and expected remaining life (e.g., a strong engine despite high km).
• Repair is relatively inexpensive (typically under 20-30% of the vehicle's current market value).
• You need to keep the car short-term and replacement costs are higher than repair.
• You plan to keep driving it and future running costs remain predictable.

If you want to better understand how a specialist buyer handles vehicles in any condition and the typical process, see our About / How it works page for context on collection, paperwork and valuation in South Africa.

When trading in or selling as-is is preferable

• Repair costs are high relative to market value (major engine or gearbox work).
• The car has recurring faults or uncertain future reliability.
• You want immediate cash or to avoid arranging tow/repairs - especially useful in remote areas around Cape Town or Durban.
• Selling to a specialist buyer who handles salvage simplifies paperwork and towing.

If your car doesn't run or has been written-off, review options on our Sell Non-Running Car page to compare selling-as-is versus costly repairs.

How to compare repair vs trade-in: a step-by-step approach

1) Get a realistic market value for your car as-is and after proposed repairs. Use local classifieds and dealer trade-in quotes. 2) Obtain at least two independent repair estimates that itemise parts and labour. 3) Factor in transfer/deregistration costs, towing and the time you’ll spend managing repairs or sale. 4) Consider tax/finance status - if the vehicle has finance against it, settlement affects your net proceeds.

Legal, paperwork and practical steps in South Africa

When you sell or trade a vehicle in SA, expect to manage or transfer ownership paperwork. If a buyer handles deregistration, confirm they follow eNatis or relevant provincial procedures and issue a signed sale agreement. If the car is under finance, contact your lender for settlement figures and ensure all parties agree on payment routing to clear the title before transfer.

For sellers who prefer not to handle towing or admin, specialist services can collect the car anywhere nationwide and manage paperwork. Learn how our process works, including free towing and paperwork handling, on the Sell Damaged Cars page.

Tips to maximise what you get

• Document service history and provide clear photos - buyers pay more for transparency.
• Get written repair quotes and compare them to trade-in offers in R.
• If selling-as-is, obtain offers from specialist buyers who handle towing and paperwork to avoid hidden costs.
• Consider the total time cost: immediate sale avoids repeated repair trips and downtime in busy centres like Johannesburg.

What happens after you choose to trade-in or sell as-is

If you accept an offer from a specialist buyer, typical steps include a final inspection, scheduling free collection, completing a signed sale agreement and arranging payment. The buyer usually handles deregistration and, if needed, settlement with a finance provider. If you trade in at a dealer, confirm whether they settle any outstanding finance and how it affects your new-vehicle deposit.
