Used Luxury Cars Best Value 2026: Depreciation Deals on BMW, Mercedes, Lexus
Used luxury cars lose 60-75% in 5 years, making 3-5 year old BMW, Mercedes, and Lexus models the best value in 2026. See which to buy and avoid.
Why used luxury cars are the best value in 2026
Luxury cars depreciate faster than any other segment, losing 60-75% of their value over five years, which creates extraordinary value for used buyers. A 2021 BMW 5 Series that cost $58,000 new is worth about $23,000 in 2026, a 60% drop. A 2020 Mercedes S-Class that cost $110,000 new is worth about $35,000, a 68% drop. A 2021 Lexus LS that cost $80,000 new is worth about $34,000, a 57% drop. The previous owner absorbed the steepest depreciation, and the used buyer gets a premium vehicle with advanced technology, superior materials, and strong performance for the price of a mainstream compact. The catch: luxury cars have higher maintenance and repair costs, and some models become money pits as they age. The key is choosing models with strong reliability records and reasonable parts costs. For buyers willing to do the research, 3-5 year old luxury cars offer the best dollar-per-feature value in the 2026 market.
The best used luxury car buys by brand
Lexus is the safest used luxury buy, because Toyota's reliability reputation extends to its luxury division. A 2021 Lexus ES ($42,000 new, $24,000 used, 43% drop) offers Camry-based reliability with luxury features, and maintenance costs are the lowest of any luxury brand. A 2021 Lexus RX ($48,000 new, $27,000 used, 44% drop) is the best-selling luxury SUV and holds value better than German rivals. Among German brands, BMW is the best used buy because the B58 and B48 engines (used in the 330i, 530i, X3, and X5 from 2019+) are reliable, and BMW's certified pre-owned program is strong. A 2021 BMW 330i ($43,000 new, $22,000 used, 49% drop) offers excellent driving dynamics. Mercedes is riskier: the W206 C-Class and W213 E-Class from 2020+ are reliable, but older models have expensive air suspension and electrical issues. Audi sits in the middle: the 2020+ A4 and Q5 are reliable, but maintenance costs are high.
The luxury models to avoid used
Some used luxury cars are cheap for a reason, and buying them can lead to thousands in repairs. Avoid the BMW 7 Series from 2016-2020, which has problematic V8 engines, air suspension failures, and iDrive electronics issues that can cost $5,000-10,000 to fix. Avoid the Mercedes S-Class from 2015-2019 for similar air suspension and electrical gremlins, plus the V12 models have catastrophic failure modes. Avoid the Audi A8 and Q7 with the 3.0T V6 from 2017-2020, which has timing chain tensioner failures costing $4,000-6,000. Avoid the Porsche Panamera and Cayenne from 2016-2019, which have air suspension and PDK transmission issues. Avoid the Range Rover and Range Rover Sport from any year, which are notorious for electrical, air suspension, and cooling system failures, with average repair costs exceeding $3,000 per year after year 5. The rule: research the specific year and engine, because luxury car reliability varies dramatically within the same model line across generations.
Certified pre-owned (CPO) for luxury: when it is worth it
For used luxury cars, CPO is often worth the premium, unlike for mainstream brands. The reason: luxury car repair costs are high enough that a single major failure can exceed the CPO premium. A 2021 BMW 5 Series CPO typically costs $2,000-3,000 more than a non-certified equivalent, but the BMW CPO warranty covers 1 year unlimited miles beyond the original 4-year/50,000-mile warranty, and includes roadside assistance. A single air suspension replacement ($3,000-5,000), turbocharger failure ($2,500-4,000), or electronics module replacement ($1,500-3,000) pays for the CPO premium. Lexus CPO is also strong, extending the warranty to 3 years/100,000 total miles. Mercedes CPO extends to 5 years/75,000-100,000 miles. The CPO also typically includes better financing rates (2-3 percentage points below standard used rates), which can save another $1,000-2,000 over the loan term. For European luxury vehicles especially, CPO is the safer used buy. Run the numbers with our <a href="/calculators/used-car-value/">used car value calculator</a>.
Maintenance and repair costs: the hidden luxury price
The purchase price of a used luxury car is only the beginning. Maintenance and repair costs for European luxury vehicles run 50-100% higher than for mainstream brands. An oil change for a BMW 5 Series costs $120-180 versus $60-80 for a Camry. Brake pads and rotors for a Mercedes E-Class cost $800-1,500 versus $300-500 for an Accord. Air suspension replacement for an Audi Q7 costs $3,000-5,000 and is a common failure after year 6. The most expensive repairs: BMW V8 engine issues ($5,000-10,000), Mercedes air suspension ($3,000-5,000 per axle), Audi timing chain ($4,000-6,000), and Porsche PDK transmission ($4,000-8,000). Budget $1,500-2,500 per year for maintenance and repairs on a 5+ year old European luxury car, versus $500-800 for a mainstream vehicle. Lexus is the exception: maintenance costs are only about 20% higher than Toyota, making it the lowest-cost luxury brand to own.

Insurance and fuel costs for used luxury cars
Insurance for luxury vehicles runs 30-60% higher than for mainstream vehicles of the same age, because parts are more expensive and repair labor rates at luxury-certified body shops are higher. A 2021 BMW 5 Series costs about $1,800-2,400 per year to insure versus $1,200-1,500 for a 2021 Camry. A 2020 Mercedes S-Class can cost $2,500-3,500 per year. Lexus is again the exception, with insurance only about 15-20% higher than Toyota equivalents. Fuel costs are higher too: most luxury cars require premium fuel (currently about $4.15/gal versus $3.45 for regular, a $0.70 premium), and many luxury vehicles have lower fuel economy due to larger engines and heavier weight. A BMW 5 Series averaging 26 mpg on premium costs about $2,000 per year in fuel for 15,000 miles, versus $1,848 for a 28-mpg Camry on regular. The combined premium for insurance and fuel adds $600-1,200 per year for a European luxury car versus a mainstream equivalent.
