Review of the 2003 Mitsubishi Diamante

  • Although the VR-X version is a step in the right direction, the Diamante is a diamond best left in the rough.

    Long list of standard features, confident brakes, capable handling (in VR-X) and quiet ride.

  • Cons

    Transmission easy to confuse, some subpar interior materials, ergonomic flaws.

  • What's New for 2003

    After introducing the sporty VR-X trim level halfway through 2002, the Diamante continues into 2003 with no changes.

Diamante ls

Vehicle: 2003 Mitsubishi Diamante LS 4dr Sedan (3.5L 6cyl 4A)

This car has been a blessing for me! Cold A/C and very comfortable to sit in! Just have a few complaints. Fuel economy is terrible, especially in the city, and showing signs of rust and paint is starting to peel on the hood! All and all this car's performance is awesome. Transmission doesn't seem to shift at the right time especially when you punch it right off the line! Using Full Synthetic Motor Oil has increased horsepower greatly and be sure to run only premium fuel in these cars to help get the most out of your gas tank!




Nice car but could of

Well I bought my Diamante used.. I loved this car when I test drove it. Beware! This car carries a high symbol for insurance rates. This car is 5 years old and has a higher symbol than most brand new cars. Not worth it to insure it . Get insurance quote before u buy. Other than the high insurance and the 19 mpg on highway (which sucks with the price gas today) ---- I'm trading it in. For cheaper insurance and better gas mileage . On the other hand the car has a nice style about it. It runs smooth. Oh and not very good in snow or slush. Parts and labor are more expensive




Beautiful car

We bought the car new in 03. Overall this car is so beautiful and rivals BMW and Lexus in my opinion. It's designed beautifully both inside and out and is unique from other luxury sedans. We have had some quality issues however. The brake light in the rear windshield constantly falls and we've taken it to the dealer 5 times. They still haven't fixed it. We have to keep it propped up. Plastics are very cheap looking. The black rubber molding in the passenger side door has had to be replaced in the front seat and the back seat is now having issues too. Also issues with paint chipping and wind noise. Glove box doesn't latch properly and hangs open a bit even when closed.

Best car out there!!

Vehicle: 2003 Mitsubishi Diamante LS 4dr Sedan (3.5L 6cyl 4A)

I love driving my car! Mine is very fast. I maintain mine and do oil changes religiously so it is still in great shape with 65,000 miles on it. It hasn't spent one day in the garage. I love the appearance, all the options, and the size. I can have my son's car seat in the middle and still have room for adult passengers on both sides of him. I have more room for people and stuff than small SUVs. The trunk space is very generous. All the luxury items without the over-inflated price tag!




Diamante is "okay"

by on
Vehicle: 2003 Mitsubishi Diamante LS 4dr Sedan (3.5L 6cyl 4A)

The stiff ride improved significantly with the addition of Goodyear Assurance tires. Overall the Diamante is a pretty good value for the money. It is reliable but had little glitches initially and I spend several days at the dealer having noises fixed and things adjusted. I am currently having trouble finding patch paint and misc. parts. I would like more power but it's adequate as is. A recent trip East gave me a low of 22 and high of 29 mpg - overall 26.54 mpg at 70+ mph all the way - I'm pleased. I will probably keep this one for a while as my "work" transportation. Too bad they stopped importing the car.




Groovy, cool wheels

I love my 2003 Mitsubishi Diamante. It has all the creature comforts that I was lookintg for. When I drive by ladies with the Infinity stereo blastin' loud, they always give me the eye. I love the feel of the leather seats. this is the best car in the world! I wish I could live in it.
