Before the Mercedes-AMG GT, there was the SLS. Built from 2010 and 2014, the SLS was a successor to the SLR McLaren and was heavily inspired by the iconic Mercedes-Benz 300SL with a gorgeous design featuring gullwing doors. While the current-generation AMG GT will bow out next year with the highly-anticipated new Black Series model, the SLS was given a special send-off with the aptly-named Final Edition.

Unveiled at the 2013 Los Angeles Auto Show and Tokyo Motor Show simultaneously, the Mercedes SLS Final Edition was built to celebrate the model's success.

Among the upgrades that distinguish the Final Edition include a carbon-fiber hood, a front splitter, a carbon-fiber rear wing lifted from the SLS AMG Black Series, and lightweight forged alloy wheels finished in matte black. Only 350 of them were built, and one of them is heading for auction to look for a new home.

This 2014 SLS AMG GT Final Edition was delivered new in the Middle East and only has one previous owner. Since it was delivered, it's been driven less than 46 miles, making it one of the lowest-mileage SLS AMG GT Final Editions you're ever likely to find. As a result, it's in immaculate condition and looks fresh out of the factory. The owner had the exterior finished in Imola Grey paintwork and the interior trimmed in quilted leather. Optional carbon-fiber side mirrors were also equipped.

Under the hood, the SLS AMG GT Final Edition is powered by a 6.8-liter AMG V8 engine producing 591 horsepower and 479 lb-ft of torque. With this setup, 0-62 mph takes 3.7 seconds, before the sports car hits an electronically limited top speed of 199 mph. Power is sent through a seven-speed dual-clutch transmission.

Many consider the Final Edition to be one of the most desirable SLS models, as it combines the subtlety of the regular AMG SLS with the track-focused Black Series. When it goes under the hammer at RM Sotheby's London auction later this month, the SLS AMG GT Final Edition is estimated to sell for between £275,000 ($354,189) and £325,000 ($418,587).
