Luxury cars attract buyers thanks to their high-end finishes, comfortable ride quality, and advanced technology. There’s also the prestige that comes with owning a car with a luxury nameplate. As a result, they come with a heftier price tag than their non-luxury counterparts. But is the extra price worth it? Or should you save money by buying a used luxury car

We determined the best luxury cars based on reliability to help you decide which premium vehicles are worth the extra cost. Because these vehicles are often leased, we also looked at the average price of 3-year-old luxury vehicles for buyers who want a luxury car without paying the expensive luxury new car prices.
