2018 Mercedes-Benz CLS CLS 450 AMG Line Edition 1

The 2018 Mercedes-Benz CLS offers varying power outputs across its lineup. The CLS 350 features a 3.0L V6 turbocharged engine delivering 367 horsepower, while the performance-oriented CLS 53 pairs a 3.0L inline-six turbo with an electric assist system for a combined 435 hp. Both variants come mated to a 9-speed automatic transmission, balancing spirited performance with fuel efficiency. As a four-door coupe, the CLS is tuned for linear power delivery and sporty handling while retaining Mercedes’ signature luxury comfort—ideal for drivers seeking both excitement and everyday usability. Those craving more extreme performance should explore AMG models with their more aggressive setups. If you’re considering one, test drives are a must. The acceleration and chassis tuning differ noticeably between powertrains, so pick what suits your needs. And remember: regular maintenance is key to keeping these engines in top shape.

The 2018 CLS makes for a compelling used luxury coupe that still holds up well today. It carries forward Mercedes' signature elegant design – the frameless doors and fastback silhouette remain head-turners. Under the hood, the 3.0T V6 turbo packs plenty of punch, paired beautifully with the buttery-smooth 9-speed gearbox while delivering reasonable fuel economy for its class. The cabin feels slightly tighter than traditional sedans, but typical Mercedes craftsmanship shines through with premium materials. The COMMAND infotainment isn't the latest generation but covers all the essentials. Word to the wise: early production models may require pricey air suspension maintenance – always check service records and scrutinize the suspension. Also test all touchscreen functions thoroughly. Its resale value sits mid-pack among rivals, with maintenance costs higher than Japanese competitors but lower than AMG models. For buyers wanting a business-savvy yet sporty four-door coupe with star power, a well-maintained CLS at the right price still delivers. Just be smart – prioritize certified pre-owned units through authorized dealers for that extended warranty safety net.

"The resale value of a used 2018 CLS 550 depends on factors like condition, mileage, service history, and optional specs—currently ranging around RM250k to RM350k, but a proper assessment is needed for an exact figure. Packing a 4.7L V8 biturbo engine, it delivers strong performance plus a premium interior, so demand remains decent in the used market, especially for well-maintained examples. The CLS’s coupe-like styling and Mercedes’ brand cachet also help prop up its value. For a precise quote, hit up local used-car platforms or dealers for a professional inspection. It’s smart to cross-shop rivals like the Audi A7 or BMW 6 Series from the same year. Pro tip: Consistent maintenance and full service records are critical for preserving value—high-end buyers always check those details."

**2018 CLS550 Common Issues (High-Performance Luxury Coupe)** Owners of the 2018 CLS550 have reported a few recurring problems, mostly related to electronics and mechanical components. The air suspension system can develop leaks or lose damping effectiveness over time, particularly if the car is frequently driven on rough roads. Regular suspension checks are recommended to keep it functioning properly. Another known hiccup is the COMAND infotainment system—it occasionally freezes or goes blank. A simple system reboot or software update usually does the trick. Under the hood, the 4.0L V8 biturbo packs serious power, but in hot, humid climates, the turbo cooling system may demand more frequent attention. Staying on top of spark plug and ignition coil replacements is key to avoiding performance dips. Fair warning: Maintenance costs for this luxury coupe are on the higher side. If you’re buying used, insist on a thorough inspection and verified service history. And given the car’s advanced tech, always opt for certified specialists for repairs—it’s the best way to keep it running like new.

The 2018 CLS has proven to be generally reliable in real-world use. Its 3.0L V6 turbocharged engine is a well-sorted powerplant, delivering smooth acceleration with reasonable fuel efficiency for daily driving. Maintenance costs are relatively manageable for this segment. The cabin showcases Mercedes' signature craftsmanship, and the electronics have held up well over time. That said, like most luxury vehicles, watch out for aging components – the air suspension in particular deserves regular inspections to avoid costly repairs down the road. One standout feature is Merc's then-new MBUX infotainment system. While packed with tech, early software versions could occasionally lag (a dealership update usually sorts this). In terms of resale value, the CLS sits mid-pack among its peers – thorough service history is key if you're buying used. Those coupe-like looks still turn heads today, though the sloping roofline does pinch rear headroom. It's better suited for small families or as a stylish commuter. Pro tip: When checking used examples, pay extra attention to transmission behavior and any suspension noises – these are common wear points on aging German performance cars.

If you're looking for an alternative to the 2018 CLS, consider the BMW 6 Series Gran Coupe, Audi A7, or Lexus GS—all offering that luxury four-door coupe vibe with a blend of sportiness and comfort. The 6 Series Gran Coupe nails precise handling and upscale interiors, perfect for driving enthusiasts. The A7 stands out with its tech-forward vibe, thanks to the Virtual Cockpit and that sleek fastback design. Meanwhile, the GS delivers plush ride quality and rock-solid reliability. For better value, the Infiniti Q60 or Jaguar XF are solid picks, packing bold styling and plenty of features. And if you’re eyeing EVs, the Tesla Model S brings next-level performance and tech, though its vibe leans more futuristic. Each of these has its own flavor, so test drives are key. At the end of the day, how it drives and fits your daily grind matters most.

The 2018 CLS 550, as Mercedes-Benz's luxury four-door coupe, delivers above-average reliability overall. Its 4.7L V8 biturbo is a proven powerplant with stable output, though be aware of common long-term wear items like seal leaks or aging ignition coils—regular inspections are key. The 9G-Tronic transmission offers buttery shifts, though some early-build models may exhibit slight lag (fixable via a software update). Watch out for pricey electronic gremlins, particularly in the air suspension and COMAND system. Always scan for stored fault codes before buying. While the CLS 550 holds value better than most rivals, expect 20-30% higher maintenance costs compared to Japanese luxury brands in the used market. If shopping pre-owned in humid climates, pay extra attention to: - Engine health (listen for timing chain noise) - Suspension bushings/air struts - Sunroof drain tubes (common clog points) Stick to factory maintenance intervals with genuine parts, and you’ll enjoy this grand tourer—just budget for the occasional electronic hiccup.
