(iSeeCars) - How reliable is the luxury car I want to buy? This question is top-of-mind for luxury car shoppers, but with limited unbiased and free resources available to consult, it can be difficult to answer. iSeeCars's objective and data-driven Reliability Rating, based on a rigorous analysis of over 312 million vehicles, addresses this lack of information by calculating each luxury car model's useful lifespan and its ability to last 200,000 miles or more. The luxury cars on this page are organized by luxury car segment and powertrain, allowing shoppers with any budget to find a reliable model. Regardless of size and exterior shape, every luxury car has to meet a minimum standard of premium features. These include a luxurious interior design, powerful engine options, advanced safety features, a smooth ride, and a high-tech infotainment system paired with a high-quality audio system, even on the base model. Optional all-wheel drive is another worthy feature for luxury car shoppers living in colder climates.The best luxury cars also offer comprehensive warranty coverage (for at least five years), an uncompromised dealership experience, and relatively high fuel efficiency – despite their strong horsepower numbers and capable performance. The advanced powertrain technology in today’s luxury cars often combines smaller, four-cylinder engines with turbocharged induction, delivering rapid acceleration and impressive fuel economy. Turbo V6 engines provide even greater performance, but the larger engine design reduces MPG ratings.If the pricing of the latest premium cars is a concern, consider shopping for older models. Many luxury brands offer Certified Pre-Owned programs, giving their used cars the same warranty coverage and peace of mind found with new cars.Although luxury automakers are less often associated with long-term dependability than mainstream automakers, they should be held to the same, if not higher, standards, considering the added cost borne by all the luxury features. The iSeeCars Reliability Ratings can help focus shoppers’ searches and guide them to a long-lasting vehicle with their desired set of premium features.
