Nunben Dixon from Gumtree Auto says buying a car is a highly personal decision. You might choose your car based on your lifestyle, taste or affordability. It stands to reason that the reasons for selling a car can vary dramatically too, depending on your needs or wants.

Here are some of the factors you need to consider, as suggested by Dixon.

“Depreciation is often the biggest deciding factor, although it varies from car to car. New cars lose value much faster than pre-owned cars. Usually about 15-30% in the first year, depending on the make and model, and up to 50% across the first three years. If you are driving a new car, you might want to hold onto for as long as you can to get the most value out of it,” says Dixon.

“Seasonality can also play a part. Convertibles, classics and sports cars sell poorly in winter, while off-road vehicles experience a slight peak. Hatchbacks are popular all year round, but actually sell quite well towards the end of the year as parents buy graduation presents or get-around for their children that are starting to drive or moving away to study.”

“January, March and September usually sees a peak in demand, while December sees demand slow down. You might decide to hold off selling to avoid the added competition or you can ride the wave of extra traffic, especially if you are selling your car online.”

There isn’t generally a perfect age to sell a car, but cars with more than 150 000km on the clock tend to fetch a lower price.

“Generally, after five years of use, failure rates go up for cars. Warranties expire, car owners let maintenance and services slip, and the accumulated miles start to take their toll on the vehicle. But if you’ve kept up with your services, replaced parts and generally keep your vehicle in good condition, mileage doesn’t have to be a deal-breaker.”

The most in-demand cars on the pre-owned market are two- to three-yearold vehicles, valued between R150 000-R250 000.

Market factors, which are outside your control, can also play a huge part in how much your car will fetch. “2017 would not have been a good time to sell your Ford Kuga, following the big recall, but your odds are much better in 2018. VW and Toyota are perennially popular, whereas up and coming brands like Haval or Geely are much harder to flip on the pre-owned market.”

Getting the absolute best value for your pre-owned car starts with purchasing the right car straight off the bat.

“Do your research before you purchase a car. Look at demand, reliability and depreciation. And once you’ve bought that car, make sure to maintain it properly to avoid losing out when you sell.”
