4. 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, a low weight, and decent performance.
Customers could get the GT with numerous engines, mostly by Ford. The lineup started with small 1.5 or 1.6-liter four-cylinder engines. However, if you wanted to experience its full potential, you could opt for the 3.0-liter V6 from a Ford or Volvo. For a brief period, they offered the Marcos GT on the American market with Volvo’s straight six, but they didn’t sell many of them.
