420 - 1985 to 1986
The 420 was launched in 1985, two years after the 425. It was simply the same car overall, only with the 2.0-litre V6 in place of the 2.5-litre unit. This model was meant primarily for the Italian market, where cars with engines over 2 litres of capacity were heavily taxed by the government during the 1980s.
2810 were produced in just two years, the model being upgraded in 1986 with an injection system, thus becoming the 420i.
Please see the description of the 425 for more details.
