The used prestige sedan market in Australia rewards buyers who take a considered approach. These are not vehicles that reveal their full picture in a brief test drive or a set of photographs. The right example, with verified provenance and an unbroken service history, is a different proposition from a similar-year car that has passed through multiple owners and dealer lots. Understanding which marques hold up, which generations represent the strongest buying opportunity, and where each model sits in the segment is the foundation of a confident decision.
This guide covers the best used luxury sedans australia buyers are actively considering, drawn from the prestige segment that MCT Motorsport knows well.
BMW 5 Series and 7 Series: the benchmark German sedans
The BMW 5 Series in its G30 generation, covering roughly 2017 to 2023, remains one of the most complete executive sedans available on the used market. The G30 refined the chassis and interior significantly over its predecessor, and the range of powertrain options, from turbocharged four-cylinder through to the six-cylinder and V8 variants, means buyers can align performance expectations with budget. The current G60 generation, introduced from 2024, uses a largely electrified powertrain configuration; buyers who prefer a conventional petrol drivetrain will find the G30 the more straightforward ownership proposition.
The 7 Series, currently in its G70 generation, occupies the flagship position in BMW's sedan range. It is a longer-wheelbase, more technology-intensive vehicle and the used examples represent a significant step up in both capability and complexity. Buyers should factor in the cost of servicing at this level and verify that any example has been maintained to the manufacturer's schedule without gaps.
Mercedes-Benz E-Class and S-Class: refinement and residual strength
The Mercedes-Benz E-Class in W213 form, produced from 2016 through to 2023, is among the strongest all-round executive sedans of its generation. It is composed, refined, and broadly well-regarded for long-distance comfort. The cabin quality and technology suite that Mercedes developed across the W213 lifecycle made later facelift variants a particularly strong used-market proposition.
The S-Class W223, the current generation, sets the standard for the full-size luxury segment globally. Used examples that have found their way onto the Australian market represent the most capable version of the model and come with a technology and comfort specification that few competitors match. At the same time, ownership costs at this level are substantial. Service intervals, tyre specifications, and the complexity of the air suspension and electronics all require attention when assessing any W223 example.
For buyers looking at the best used luxury sedans australia has to offer at a flagship level, the S-Class and the BMW 7 Series G70 are the two reference points around which everything else is measured.
Audi A6 and A8: precision engineering with strong technology
The Audi A6 in C8 specification, from 2018 onwards, brought a significant improvement in interior quality and technology over its predecessor. The virtual cockpit system and the dual-screen infotainment configuration became defining features of the generation. The mild-hybrid integration on certain variants is worth understanding before purchase, as it affects service requirements and the nature of the powertrain.
The A8, in its D5 generation, is Audi's equivalent of the flagship category. It is a car known for its quattro all-wheel drive system, long-wheelbase comfort, and a cabin that competes directly with the S-Class at the premium end of specification. As with any flagship luxury sedan, used buyers should scrutinise the service history carefully and confirm the air suspension and active systems are in good order.
Genesis G80 and G90: the considered alternative
Genesis has established a credible position in the Australian prestige market in a short time. The G80 and G90 offer a level of specification, warranty backing, and presentation that challenges the established European marques on value terms. The G70, Genesis's entry-level executive sedan, is a driver's proposition with European-tuned dynamics. For buyers willing to look beyond the traditional German trio, Genesis represents one of the more interesting choices among the best used luxury sedans australia buyers can consider at this moment in the market.
Lexus ES and LS: reliability as a genuine differentiator
The Lexus ES and LS sit apart from their European counterparts in one consistent and well-documented area: long-term reliability and ownership cost predictability. The ES is a front-wheel-drive executive sedan built around the hybrid powertrain and a comfort-focused character. The LS is the flagship, a rear-wheel-drive, full-size luxury sedan that competes directly with the S-Class and A8 at the top of the segment.
Both marques carry a service reputation that is hard to match in the prestige category. For buyers who prioritise lower maintenance friction and a more predictable total cost of ownership, the Lexus range is a serious consideration when looking at the best used luxury sedans australia offers.
Maserati Ghibli and Jaguar XF: lower-volume marques with distinct character
The Maserati Ghibli and Quattroporte occupy a specific position in the prestige segment. They are lower-volume, Italian-badged alternatives to the German mainstream, and their appeal is tied to character, sound, and the distinctiveness of the marque rather than segment leadership in technology or residuals. Buyers interested in this end of the market should approach provenance particularly carefully. Full dealer service history and verification of any significant repairs are non-negotiable with vehicles of this kind.
The Jaguar XF remains in production and offers a considered British alternative in the executive segment. The XJ, Jaguar's full-size saloon, was discontinued and examples that appear on the used market are worth assessing carefully in terms of parts availability and long-term support.
What to look for across the segment
Across all the best used luxury sedans australia buyers will encounter, a handful of considerations apply consistently. Service history continuity matters more than age or mileage taken alone. Factory specification, particularly where vehicles have been modified or had options removed, affects residual value and buyer appeal at point of resale. Ownership lineage, how many owners and in what context the vehicle was used, is worth establishing before committing.
