Mitsubishi Diamante: V6 saloon and estate, generations and what to check
Mitsubishi Diamante — the more luxurious saloon and estate, produced from 1990 to 2005. Mostly sold in Japan and the USA, limited availability in Europe. We briefly look at two generations, engines, and what to check when buying.
Diamante in brief
The Diamante was Mitsubishi's top-tier mid-size model, focused on comfort and a rich specification. Offered as a saloon and estate, with front-wheel drive and V6 engines.
Today, it's a rare car, and its value depends more on condition than on specification.
Which generation to choose
The first generation (1990–1995) is a bit simpler, with a classic design. The second generation (from 1995–1996 to 2005) is more modern, has more equipment, and uses more advanced V6 engines.
For most buyers, the second generation is the better choice due to greater comfort.
Engines and gearboxes
The Diamante used V6 engines ranging from 2.5 to 3.5 litres. The most common in the US market is the 3.5 V6 (around 205–210 hp). The gearbox is an automatic, 4-speed.
The car is heavy and consumes quite a bit of fuel, but it rides smoothly.
What to check when buying a used Diamante
Check the operation of the gearbox and engine oil leaks, as well as the history of the V6 timing belt replacement. Due to its age, it's worth inspecting the bodywork and suspension.
Check the electrical equipment – windows, seats, air conditioning. Parts may need to be sourced, as the car is rare.
