5 Luxury Brands With the Most Expensive 10-Year Maintenance

Following a routine maintenance plan will keep your vehicle running efficiently and help prevent costly repairs from arising. Regular oil changes, tire rotation, and fluid level checks can go a long way in extending the lifespan of your vehicle.

While auto maintenance is crucial, it can also be expensive. Several luxury brands are notorious for having very high maintenance and repair costs, adding to the overall cost of vehicle ownership.

Car Edge analyzed extensive data to determine which luxury brands are the most expensive to maintain over a 10-year period. The consumer advocate claims having this information will help you “determine over time whether your car is a great value, or a money pit on wheels.”
