It's the 1998 Brabham-Viking Cosworth Sports Racer!
Straight-4, 1600cc, 240hp with twin Weber carbs, cross flow head and dry sump Cosworth engine, Brabham Formula 2 suspension with adjustable shocks and springs, Girling alloy disc brakes, Hewland Mark VIII / IV 4-speed gearbox. It should be quite a nice ride!
