The Marcos TSO is a sports car manufactured between 2004 and 2007 by Marcos. It features a Chevrolet V8 engine in either {{cvt|350|bhp|0}} or {{cvt|400|bhp|0}} versions. The car's components were CAD designed in England, with chassis engineering carried out by Prodrive.

In 2004, the 5.7-litre Chevrolet Corvette (LS1) V8 TSO GT was announced, but solely for the Australian market. It was joined in 2005 by the GT2 for the European market. The T50 GT2 was tested on British Motoring Show Top Gear by presenter Richard Hammond, the episode airing in December 2005. Hammond broadly praised the car as a mix a of an American muscle car and a traditional British Sports car, though criticised its reliability issues and tendency to oversteer. The car completed a lap of the track in 1:28.2.{{Cite web |title=Top Gear Track lap times |url=https://fastestlaps.com/tracks/top-gear-track |access-date=2024-04-13 |website=FastestLaps.com |language=en-US}}

In 2006 Marcos announced the TSO GTC, a modified version of the current TSO with a racing suspension, racing brakes and a rear diffuser. The car still featured a Chevrolet-sourced {{cvt|420|bhp|0}} V8. A {{cvt|462|bhp}} Performance Pack was also available. With the extra power from the Performance Pack the TSO GTC accelerated to {{cvt|60|mi/h|km/h}} in 4.1 seconds and to {{cvt|100|mi/h|0}} in 8.5 seconds. With the bigger brakes, 340 mm AP Racing brakes, the TSO GTC delivered a 0-100-0 time of 12.9 seconds. With the extra power, its 50 to {{cvt|70|mi/h|km/h}} time was 2.1 seconds. Top speed was over {{cvt|185|mph|km/h}}.
