For a 2014 BMW 535i GT with 72,000 km—one of the more reliable used cars in its luxury segment—routine maintenance services (oil change, filter replacement, inspection) average $300-$500 at independent European car specialists or reputable used car dealers. Major services at 100,000 km (including spark plugs, transmission fluid, and brake fluid flush) typically cost $1,200-$1,800, which is important to consider when evaluating used car values and long-term ownership costs. With its 306-horsepower engine, comfortable adaptive suspension, and 65-liter fuel tank providing over 600 km of highway range, this vehicle is well-suited for long-distance driving. Its rear-wheel drive layout and balanced weight distribution offer stable handling on extended trips, and the 72,000 km mileage is still within the low-to-mid range for this model, making it a reliable and worth buying choice for frequent highway use with proper ongoing maintenance.
