The Dilemma:Choosing Between Used Electric and Petrol Cars

In this article, we’ll dive into the specifics of choosing between used electric and petrol cars, analysing popular models, costs over time, and the typical issues to look out for. The UK’s used car market is facing a major shift, driven by rising interest in electric vehicles (EVs) and changing environmental regulations. For buyers, the decision often boils down to this: should you opt for a traditional petrol-powered car, or go electric? While both options come with their advantages, understanding the nuances of cost, maintenance, and performance is key to making an informed decision.

Whether you’re considering an electric vehicle like the Tesla Model 3 or a petrol workhorse like the Ford Focus, here’s everything you need to know to make the right choice.

Electric vs Petrol: What You Need to Know

The rise of EVs in the UK is transforming the automotive landscape. Leading models like the Nissan Leaf and Tesla Model 3 have become more affordable and accessible on the second-hand market, offering significant benefits in terms of fuel costs and environmental impact. For example, the Nissan Leaf, known for its reliability and low running costs, offers a range of about 168 miles per charge. On the higher end, the Tesla Model 3 can deliver up to 267 miles on a single charge​.

The advantages of electric vehicles are clear when it comes to cost-per-mile and maintenance. With fewer moving parts, EVs tend to suffer fewer breakdowns and require less frequent servicing. However, there are still challenges with battery degradation and the need for reliable charging infrastructure. In contrast, petrol cars like the Ford Focus or Vauxhall Astra remain popular for their lower upfront costs and widespread fuel availability. They also provide a longer range, typically around 350-500 miles per tank​.

Yet, while petrol cars may seem more convenient today, their long-term viability is being challenged by tightening emissions regulations and increasing fuel prices. With the UK planning to phase out new petrol and diesel car sales by 2030, the scales are increasingly tipping in favour of electric cars.

Maintenance Costs: How Do They Add Up?

When it comes to maintenance, the differences between EVs and petrol cars become more pronounced. Electric vehicles are often praised for their simplicity—fewer moving parts means fewer components that can break down. This translates into lower annual maintenance costs for EV owners. However, some significant expenses can crop up, particularly around battery replacement. Batteries in EVs like the Nissan Leaf or Tesla Model 3 tend to last between 8-10 years, but when they need replacing, the cost can range from £3,000 to £8,000​.

Charging systems can also be a weak point. While home charging is cost-effective and convenient, public charging ports can suffer from wear and tear. Replacing a faulty charging system can cost around £500 to £1,000. The good news is that EVs don’t require oil changes or exhaust system repairs, saving owners several hundred pounds per year​.

On the other hand, petrol cars may seem cheaper at first glance, but their more complex engines come with a long list of maintenance needs. For example, oil changes—required every 10,000-15,000 miles—cost about £100 to £200 annually. AUTODOC states that over time, essential parts like the catalytic converter (prone to theft in models like the Ford Focus) may need replacing, which can set you back around £200 to £600​.

Engines in petrol cars can also suffer from more severe wear. Timing belts need to be replaced after around 60,000 to 100,000 miles to avoid catastrophic engine damage. This replacement costs around £300 to £600, but if the belt fails, the cost can jump to over £1,500 due to engine repairs​. Exhaust systems, especially in older cars, are also prone to rust and damage, leading to potential repair bills of up to £800.

Overall, while petrol cars might initially seem like a budget-friendly option, the cumulative costs of regular servicing, emissions-related repairs, and higher fuel expenses often outweigh the simplicity and low-maintenance nature of electric vehicles over time.

The Costs of Ownership: What to Expect

Electric cars are, on average, cheaper to run than petrol cars. In terms of yearly running costs, data shows that EVs typically save owners £528 annually​. This figure factors in the lower fuel (electricity) costs, reduced maintenance needs, and exemptions from road tax (until 2025). Additionally, EVs are exempt from charges in Clean Air Zones (CAZ), such as London’s ULEZ, which could save urban drivers up to £15 per day​.

On the petrol side, while the initial purchase price of a used car like the Ford Focus may be lower (typically around £10,000-£15,000), the running costs are higher. Petrol itself is more expensive per mile compared to electricity, and regular servicing is a must to keep the car running efficiently.(subject to country)

When considering the lifespan of both types of vehicles, EVs tend to last longer. With fewer parts to replace and less wear on key components like the brakes (thanks to regenerative braking systems), electric cars can comfortably reach 200,000-300,000 miles​. Petrol cars, while durable, typically start experiencing more significant issues after 150,000-200,000 miles, with major engine repairs becoming more frequent​.

The Future of Ownership: Importing Cars from Abroad

For some buyers, importing cars from the US or Asia is an attractive option to access specific models or potentially better deals. However, the costs and logistics of importing a car are substantial. Shipping fees alone range from £2,000 to £5,000, with additional taxes and duties potentially adding another 10-20% to the car’s price​. Moreover, imported vehicles may require modifications to meet UK standards, such as changing the lights or emissions system, which can cost £1,000 to £2,000.

Beyond the financial outlay, there are practical considerations as well. Imported EVs might face issues with the compatibility of charging systems, while petrol cars could require hard-to-find spare parts. In the long run, the cost and effort of maintaining an imported vehicle can erode any initial savings​.

Final Thoughts: Making the Right Choice

So, which is the better option: a used electric vehicle or a petrol car? The answer largely depends on your driving habits, budget, and long-term goals. If you’re focused on lower long-term costs and environmental sustainability, an electric vehicle offers substantial benefits. Cars like the Tesla Model 3 provide great range and cutting-edge technology, making them a future-proof option. However, they come with higher upfront costs and potential battery replacement expenses down the line.

For those looking for short-term savings and easy access to infrastructure, a petrol car like the Ford Focus remains a practical choice. The initial purchase price is lower, and for drivers who cover long distances or don’t have easy access to charging points, petrol’s availability is still a significant advantage.

As the UK edges closer to its 2030 ban on new petrol and diesel vehicles, electric cars are becoming increasingly attractive. With government incentives, growing charging infrastructure, and reduced running costs, the future of the UK’s car market seems destined for an electric revolution. But for now, both petrol and electric cars still have their place in the hands of the UK’s used car buyers.
