Used Luxury Sedans vs New: When Depreciation Wins

The Smart Default: A Used Flagship Beats a New Base Model

A used luxury sedan is a pre-owned high-end four-door car that has already taken its steep early depreciation, letting buyers access flagship comfort, performance, and prestige for the price of a new base-model alternative that offers fewer features, less power, and a lower brand status within the same total budget window.

For most shoppers with a fixed budget, the smartest move is a low-mileage used flagship sedan rather than a brand-new base model. Luxury car depreciation is so steep in the first years that it pulls once-unobtainable models into reach, while new cars at the same price deliver less drama and presence. The clearest example is the first-generation Rolls-Royce Ghost: early models with low mileage now sit in the same price band as a brand-new base Mercedes S-Class, despite being the “entry-level” Rolls-Royce that originally sat far above regular luxury sedans in the market. If you care more about how the car feels and what it says about you than about having the absolute newest plate, depreciation is working in your favor.

Case Study 1: Rolls-Royce Ghost vs New Mercedes S-Class

If you are shopping in new Mercedes S-Class value territory, you should start your search with the first-generation Rolls-Royce Ghost. Early Ghosts were introduced as a more agile, youthful companion to the larger Phantom, aimed at “younger, more energetic buyers” who still wanted ultra-luxury refinement. Under the hood of the pre-facelift Series 1 is a 6.6-liter twin-turbocharged V12 that makes 563 horsepower and 575 lb-ft of torque, driving the rear wheels through an eight-speed automatic transmission. That is effortless power and wafting capability a new base-model luxury sedan cannot match.

Meanwhile, a new Mercedes S-Class offers cutting-edge tech, a fresh warranty, and the security of zero previous owners. The S 500 4Matic is equipped with a 3.0-liter inline-six that makes 442 horsepower and 443 lb-ft of torque, while the S 580 4Matic uses a 4.0-liter twin-turbo V8 with 530 horsepower and 553 lb-ft. A new S-Class Sedan comes with a four-year/50k-mile comprehensive warranty, though you still need to budget for regular servicing. If you prioritise maximum prestige, cabin opulence, and that V12 experience over the latest interface and warranty, the used Ghost is the more compelling buy at similar budget levels.

Case Study 2: AMG S63 Coupe — Depreciation as a Performance Hack

Performance-focused buyers should look hard at the Mercedes-AMG S63 Coupe as proof that luxury car depreciation can be your best ally. This big coupe was built as the ultimate S-Class offshoot, offering the same cocooning comfort with serious grand-touring pace. At launch, it used a 5.5-liter twin-turbocharged V8 hand-built at Mercedes-AMG headquarters, delivering 577 horsepower and 664 lb-ft of torque, and firing the car to 60 mph in about 3.9 seconds. Later facelifted models switched to a 4.0-liter twin-turbo V8 with 603 horsepower and the same 664 lb-ft, dropping the 0–60 mph sprint to 3.4 seconds.

The S63’s depreciation has been brutal, shedding around 57% of its original value over six years, which means buyers now step into serious power and craftsmanship for the cost of a new mid-range luxury model. Across both new and used markets, the AMG S63 Coupe comes out as the cheaper buy than the equivalent Bentley grand tourer. If you can budget for big-tyre and high-end brake bills, and accept that Airmatic air suspension components may eventually require expensive attention, the S63 Coupe is the value sweet spot for drivers who crave performance and opulence in equal measure.

Total Cost of Ownership: Used Luxury vs New Mainstream

Choosing between a used luxury sedan and a new mainstream or entry-level luxury model means thinking beyond the purchase price. Some luxury brands have reputations for more manageable ownership costs; for example, Lexus models are known for relatively low maintenance, depreciation, and insurance expenses compared with more exotic badges. At the other end of the spectrum, maintaining a Rolls-Royce Ghost in good condition averages about $3,900 per year according to dealership estimates, with servicing intervals depending on how you drive. That is before you add consumables and any unexpected repairs.

High-performance models like the AMG S63 Coupe bring extra ongoing costs: large tyres that cost a few hundred each, premium compound-steel brakes, and the possibility of spending thousands if Airmatic air suspension components fail. By contrast, a new mainstream sedan or lower-tier luxury model may have a longer warranty, cheaper parts, and more predictable servicing, but you give up the theatre of a V12 or hand-built V8. If you are prepared to build a healthy maintenance and repair buffer into your budget, used luxury sedans and coupes offer more car and more brand cachet than a new base model at a similar outlay.

Buy if / Skip if

• Buy the Rolls-Royce Ghost if you want ultra-luxury V12 power and prestige for the cost of a new base-model luxury sedan and accept higher running costs.
• Skip the Rolls-Royce Ghost if you are uncomfortable with an average maintenance spend in the thousands per year and prefer lower, more predictable servicing costs.
• Buy the Mercedes-AMG S63 Coupe if you want one of the best ultra-luxury performance coupes on the used market and can budget for premium tyres, brakes, and suspension work.
• Skip the Mercedes-AMG S63 Coupe if you prioritise low operating costs over 577–603 horsepower and are worried about potential Airmatic air suspension repairs.
• Buy the new Mercedes S-Class if you value a fresh warranty, the latest tech, and 3.0L or 4.0L engines with up to 530 horsepower over maximum badge prestige.
• Skip the new Mercedes S-Class if your priority is the most opulent cabin and brand image for your budget, even if that means owning a pre-owned flagship like the Ghost instead.
