2018 Luxury Cars You Should Probably Avoid

Key Features to Look For in 2018 Luxury Vehicles
Adaptive Cruise Control
This semi-autonomous feature maintains a safe distance from the car ahead, making highway driving safer and more relaxed. Many 2018 luxury vehicles offered this as standard or optional, especially from brands like Audi, BMW, and Volvo.
Apple CarPlay / Android Auto
By 2018, most luxury automakers had started integrating smartphone compatibility, allowing seamless access to navigation, calls, messages, and music through your car’s infotainment system. Make sure your chosen model includes this — some base trims may not.
Premium Sound Systems
Whether it’s Burmester in Mercedes, Bang & Olufsen in Audi, or Harman Kardon in BMW, a premium sound system elevates the driving experience. These systems offer crystal-clear audio and deep bass, ideal for long drives or commutes.
Heated & Ventilated Seats
Many 2018 models came with multi-zone climate control and front-seat heating/cooling. These comfort features are often taken for granted but make a big difference in daily usability.
Reliability: What to Expect in Used Luxury Cars
While most 2018 luxury cars offer great build quality, their long-term ownership costs can vary drastically. Luxury vehicles often carry higher costs for parts and repairs. To avoid potential problems, take these key precautions:
- Get a pre-purchase inspection (PPI) from a certified mechanic to uncover hidden issues
- Review owner forums and reliability ratings from sources like J.D. Power and Consumer Reports
- Check service history and confirm timely oil changes, brake services, and software updates
- Prefer Certified Pre-Owned (CPO) models, which often come with extended warranties and multi-point inspections
Following these steps can help you sidestep expensive repairs later and give you added peace of mind as a luxury car owner.
Are 2018 Luxury Cars Fuel Efficient?
Surprisingly, yes — especially when you opt for hybrid or diesel variants. Many 2018 models combined performance with eco-conscious engineering to balance power and efficiency.
- Volvo XC90 T8 Hybrid: 25–27 mpg combined; ideal for families seeking fuel savings
- Lexus RX 450h: ~30 mpg; one of the most fuel-efficient midsize luxury SUVs
- BMW 530e: Plug-in hybrid offering up to 72 MPGe with electric driving range
These models give you the best of both worlds: refined luxury and lower fuel costs — something especially valuable in today’s high fuel price environment.
Financing and Insurance Tips
Financing and insurance can make or break the ownership experience of a used luxury car. Here are a few key tips:
- Insurance: Expect higher premiums due to advanced tech and repair costs. Compare quotes from multiple providers and inquire about discounts (e.g., low mileage, safe driver).
- Financing: Credit unions often offer more competitive interest rates than dealership financing options. Also, see if the vehicle is eligible for a Certified Pre-Owned (CPO) program, which may include more favorable terms and extended warranty coverage.
- Depreciation Tip: Luxury cars lose 40–60% of their value in the first 3 years. Buying in 2025 means you’re avoiding the steepest part of the curve, allowing you to enjoy premium quality at a significantly reduced cost.
Buying smart today can mean luxury without regret tomorrow.
Where to Buy 2018 Luxury Cars Safely
- Certified Pre-Owned Dealers (CPO programs)
- CarMax or AutoNation with warranties
- Private sellers — with PPI & Carfax report
- Avoid shady imports or salvage-title vehicles.
