20. Marcos GT
Produced from 1964 to 1971 and again from 1981 to 1990, the Marcos GT was the most popular and interesting model from this company. Basically, it was a kit car they built on a custom chassis with a choice of engines. The Marcos GT was a relatively affordable but capable sports car with aggressive styling, low weight, and decent performance numbers.
The GT came with numerous engines, mostly by Ford. The lineup started with a small 1.5 or 1.6-liter four-cylinder. However, if you want to experience its full potential, you could opt for the 3.0-liter V6 from Ford or Volvo. For a brief period of time, the Marcos GT was available on the American market with a Volvo straight-six engine, but they didn’t sell many cars.
