When buying a diesel car, one of the key questions to consider is whether to prioritise lower mileage or a newer model. Diesel cars are known for their fuel efficiency and longevity, making them a popular choice for high-mileage drivers. However, with increasing emissions regulations and changing market trends, the car that you choose now can have long-term financial and practical implications.
When choosing between a low-mileage diesel car and a newer model, here are some points to consider.
Emissions and compliance
Newer diesels are more likely to comply with Euro 6 emissions standards, which are required for avoiding ULEZ charges in major cities. If you drive in urban areas, a newer model may save you money on emissions-related fees. An older, low-mileage diesel may still meet older emissions standards (Euro 5 or below), but could result in some additional costs if you drive in regulated zones.
Reliability and maintenance costs
A newer diesel car will typically have fewer mechanical issues, thanks to updated technology and manufacturer warranties (if applicable). And while a low-mileage car may have less wear and tear, age-related issues (such as rubber seals degrading or electronic components failing) could arise, especially if the vehicle hasn’t had much use.
Resale value
A newer car will depreciate faster in the initial years, but if it meets current emissions regulations, it may retain better resale value in the future. A low-mileage diesel might hold its value better if it is a desirable model, but older diesels are becoming less attractive due to emissions concerns.
Fuel efficiency and performance
Newer diesel engines tend to be more fuel-efficient and may offer better performance due to improved engine technology. However, a well-maintained older diesel with low mileage can still deliver excellent fuel economy, though it might not have the latest efficiency features.
Insurance and Running Costs
Newer cars often come with higher insurance costs but may be cheaper to maintain in the short term due to warranties; older vehicles can have lower insurance premiums but may require higher maintenance costs as they age.
Low mileage and newer models both have their pros and cons, and the area that you decide to sacrifice will depend on your driving habits and where you plan to use the car. If you frequently drive in city areas with emissions regulations, a newer diesel car that meets Euro 6 standards is the smarter choice. Hoewever, if you mostly drive in rural or motorway settings and don’t need to worry about emissions zones, a well-maintained, low-mileage diesel can offer better value. And if long-term costs and resale value are a concern, newer models are likely the safer bet as older diesels may continue to lose favour.
If you are in doubt, head to your local dealership and ask for a breakdown of the pros and cons, and take a look at the options and prices available. For more advice, follow Trust A Garage on Facebook or Twitter.
