A $448,610 limousine will revive the Maybach nameplate, and the first year's allocation is already sold.
Mercedes-Benz Australia spokesman Jerry Stamoulis says 12 cars were allocated for 2015 and they've already been ordered.
"To put that in perspective we sold 13 of the previous Maybachs in a decade ... but they were million-dollar vehicles," Stamoulis says.
The Mercedes-Maybach S600 will headline the Mercedes-Benz stand alongside classic and contemporary models from a 1967 M-B 600 Grosser to the AMG GT S.
Mercedes dropped Maybach as a separate brand in 2011 and the reprised nameplate now tops the S-Class range as a sub-brand for bespoke luxury, in much the same way as AMG is the performance offshoot.
The maker won't confirm future Maybach models but a coupe and SUV are both likely additions to the line-up.
Mercedes says the new car "melds the perfection of the S-Class with the exclusivity of Maybach" and is "aimed at customers for whom status is important".
Propulsion comes from a twin-turbo V12 and the S600 is 200mm longer than a regular long-wheelbase S-Class.
Consequently there's voice amplification so that the chauffeur can converse with the rear occupants, even though Mercedes touts the Maybach as having the world's quietest rear compartment.
Other standard items include reclining rear seats with heating, cooling and massage functions, Burmester audio, adaptive cruise control and the Magic Body Control suspension that scans the road surface and pre-loads the dampers to keep the cabin level when it detects a bump.
A refrigerator and silver-trimmed champagne flutes mean beverages can be had in style. Occupants can breathe ionised, filtered air — scented optionally with agarwood essence.
The S-Class range dominates the large luxury market in Australia and accounts for more than 40 per cent of the 558 vehicles sold in that segment to date this year.
Joining the S600 will be a special edition SL roadster built to commemorate the 60th anniversary of the 300 SL's win at the 1955 Mille Miglia in Italy.
The SL "Mille Miglia 417" — the 417 stands for the race car's number — can be ordered as a six-cylinder SL400 or, for a premium of $15,900, the V8 SL500.
The price includes red highlights inside and out, lightweight AMG Performance wheels, black paintwork, high-quality leathers, carbon-fibre inserts and AMG Line seats.
