1999 Mitsubishi Diamante Super Saloon 3.0 V6


Terrific car if kept serviced


On the whole, I've never had a problem with this car since the day I brought it.

General Comments:

One of the major reasons I've never had a problem with this car in all the 10 years I've had it, is due to regular services. The car has always preformed well, and gives me the power when I need it.

Would you buy another car from this manufacturer? Yes

1999 Mitsubishi Diamante Super Saloon 3.0 V6


Don't even think about it... Don't buy a Mitsi!


Water pump failure after 8000km driving. Cambelt shredded, valves bent.

Car "conked out" after start-up occasionally.

General Comments:

At face value this car has strong performance and a comfortable interior with plenty of features, which delivers reasonable fuel economy.

This car (when it worked) was a great car on long trips, could overtake anything, and handled surprisingly well for its size.

But that's where the fun ends... This car had a catastrophic water-pump / cambelt failure despite it being replaced 8000km ago.

I was then caught in the middle of 2 Mitsubishi dealers fighting over who was to blame! Car wasn't the same after its eventual repair.. transmission was slippy and the car wouldn't idle properly after startup.

Will NEVER own a Mitsubishi again.

That is not a review. All simple things to fix if care was taken. You got screwed and should have fought the dealers about it.

I find this review to make no sense what so ever.

If you have a cam belt broken that is the fault of the owner not the car. It is a lack of maintenance.

As for the car sales men arguing. That is their affair. Tell them to resolve it. Telling people that this car is trash because it broke a cam belt is silly.

No maintenance can prevent the cambelt from going.

Uh, what? A cambelt is a maintenance issue - it is to be replaced at particular intervals (together with the tensioner, rollers, and often the water pump, if it is run by the cambelt). Typically replaced at anything from 100-120K km.

Thanks. This review was helpful for me looking at a good deal on a Diamante right now.

Re some of the other comments... there could be 10 other people reading this, thinking hey my Diamante cam-belt went ridiculously early too! Personal experiences are all subjective, but any information should be appreciated on the site. I'd never buy a Subaru Forester (repeated oil leaky motor and right again wrong again clutch) again. I would buy a Nissan Pulsar (clutch cable broke at 280,000km, never spent anything before or after that) again in a heartbeat, but that's only my experience.
