Pretty decent car

Vehicle: 1998 Mitsubishi Diamante

I bought my Diamante for $1200 and I'm not disappointed. It has problems starting even after i replaced the starter but she runs. Smooth riding car. I used to have a 2011 Kia soul and my Diamante handles a lot better. I wasn't expecting a nice engine but I'm amazed at how nice it is. One big problem i have with it is 3 of my door handles are broken. I know someone who had the same problem with theirs. Another small problem i have with this car is it feels a little cramped on the inside. My knees want to rest on the wheel. She's old and needs some more work done but for a $1200 car with 125,000 miles on it I'm very happy with it.

Idle miss fire, electrical problem,

Vehicle: 1998 Mitsubishi Diamante

Just bought a 1998 Diamante for 2,700, after getting new tires and fixing a bad front brake caliper it rides nice. I am still working on what I think is an electrical problem. The doors unlock on their own at random and the car can be on or off. Also,the engine idle miss fire still have not figured out. Check engine light is not on. Runs great but still need to figure out these problems befor I say its a good car.

What a bargain

I bought my LS for 12,500 in 2003 and have never had a problem with it. It is faster than the Altima and Camry, and has beautiful Leather and wood inside. I get 30 mpg on the highway.

I've had this Diamante since early 2002. I love its look, the way it (used to) drive, and the driver comfort. As the years went on & I put more miles on it, of course, more went wrong with it. It's down right now, needing its third alternator. It has over 197,000 miles on it, though, and overall, I'm pleased with its life performance. It has a power steering problem (seems like fluid leak) that neither of my mechanics can fix. In the last 3 months, the steering has also become a bit less reliable - you have to turn the wheel more if you round a curve at over 35 mph.

Goo buy for a used

Vehicle: 1998 Mitsubishi Diamante

I bought this 98 Diamante with 156K miles in it. So far I've had it for few months and no problem at all as far as maintenance. The only issue I have is the antenna makes this weird noise when I turn the radio on and it doesn't want to go down when I turn the radio off. The paint in the back if oxidizing but I think the previous owner really never took care of the waxing part. It's a fun car to drive with the luxury feel to it. I recommend buying one.

Solid and safe

I was driving my Diamante last weekend and hit a patch of black ice while taking a turn on a raised interstate. My car went into a spin and hit a concrete sidewall at about 35-40 MPH. It bounced off the front and back left bumpers before stopping. The only damage is to the bumpers and lights. The car still drives straight and has no mechanical problems, but most important of all, my two passengers and I are unhurt. This is one solid and safe car.

I drove the Diamante and Infiniti I-30 back-to-back. There are several reasons why I like the Diamante better....

The "Diamante" is launched....

I have a 1999 Mits Diamante that was pulling around turns and shaking at speeds around 50 to 60 mph. This was driving my wife crazy because it wasnt doing it all the time just on hard turns....
