Vehicle overview
To achieve success in the near-luxury market, an automaker must possess a strong brand image that consumers associate with prestige. Mitsubishi does not, and this partly explains the dismal failure that the first Diamante luxury sedan suffered in the United States. It wasn't a bad car, just a little dull looking and loaded with so much techno-wizardry that it cost far more than its perceived worth. That changed last year, when the Diamante appeared worth more than its price. For 1999, Mitsubishi builds upon last year's success, offering more standard equipment than before.
The same 3.5-liter V6 drives the front wheels, making 210 horsepower and upholding the Diamante's standing as one of the most powerful sedans in its class. The Diamante will go from zero to 60 in about 8.5 seconds, and, if you make this Mitsu perform this way often, the four-speed automatic transmission is supposed to learn that you're a lead foot, and adjust itself accordingly.
Exterior styling features a chiseled, BMW-like appearance that is bolder than the smooth silhouette of the previous car. Chrome appears in the window moldings, surrounding the license plate, grille trim and alloy wheels. For 1999, the Diamante displays a centered Mitsubishi Motors decklid badge. The Diamante's interior is tastefully trimmed, though the stereo is fitted with a ridiculous number of buttons. Gauges emit a Lexus-like glow at night, and the automatic climate controls feature innovative pictograms to convey fan mode.
Standard features now include driver and front passenger illuminated visor mirrors, front and rear map lights and power trunk and fuel door releases. Our biggest complaint about the Diamante last year, the lack of traction control, has been addressed and is now offered as an option. Both traction control and heated front seats are available for 1999 with the new Platinum Package. To top it off, Mitsubishi has added a new tan color seat fabric selection and three new exterior paint colors: Richmond Red Pearl, Lexington Green Metallic and Platinum White Pearl.
For 1999, the Diamante's MSRP is less than $28,000 including destination charge- that's $5,000 less than the 1998 Diamante LS and about $8,000 less than the 194-horsepower Mercedes-Benz C280, though the Benz provides standard traction control. This year's Diamante is priced about the same as the Acura 3.2 TL, but the Acura gets you 15 more horsepower and heated seats standard. Both the Benz and the Honda have superior transmissions and are better cars overall.
Cost to DriveCost to drive estimates for the 1999 Mitsubishi Diamante 4dr Sedan and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $3.29 per gallon for regular unleaded in Utah.

1999 Mitsubishi Diamante 4dr Sedan
When I first got my Diamante I was extremely excited. I thought the interior was amazing! It was semi luxury> leather seats, seat warmers, memory seating, it was nice. Then out of no where my heater stopped working along with my radio after my first 2 months. Now my car randomly dies took it to 4 different shops, no one can figure it out. I bought the car for 3800 and have already put … $3000 worth of electrical work into it. The ride sounds loud and not that smooth. Its a nice car but beware it is known to have electrical problems and they are not cheap!
Why i love this car....

1999 Mitsubishi Diamante 4dr Sedan
Car was bought used with 28000. Took out an extra warranty which took care of all the quirks in the beginning. Other than normal maintenance, this car is the best car we have ever owned. Love driving it. The pickup is great.

1998 Mitsubishi Diamante LS 4dr Sedan
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.
