The Diamante receives a few minor styling changes that include a revised front fascia and a new front grille on the outside and a redesigned center console and dash on the inside. A Sportronic automatic transmission, projector beam foglights and a 270-watt Infinity stereo are now standard on the LS and VR-X. Additionally, all VR-X models get new sport taillamps and a rear spoiler, while the base ES gets upgraded interior fabric.

Edmunds says

Although the VR-X version can be mildly entertaining, the Diamante is a diamond best left in the rough.

One of the top cars for me

2004 Mitsubishi Diamante LS 4dr Sedan (3.5L 6cyl 4A)

I didn't want to buy the Diamante initially because of size or fuel scares. The Diamante has surpassed all my expectations, the car is luxurious, lots of standard extras sometimes I need some engine power to get out of difficult road situations. This car has all the power needed and then some. The traction control has saved me a couple of times also. ABS is also there. The gets 20.5 …

Great Car

2004 Mitsubishi Diamante VR-X 4dr Sedan (3.5L 6cyl 4A)

After owning several cars over my lifetime I can say this is definitely the best so far. The car is very reliable, inexpensive to own, gets great mileage (20-24 city and 32-38 highway depending on my lead foot). The engine has a lot of power if you need it to. Taking turns sharp will automatically throttle the engine to keep you from losing control (did I mention my lead foot?). …

2004 Mitsubishi Diamante VR-X 4dr Sedan (3.5L 6cyl 4A)

A very nice vehicle, especially when figuring in the value. Priced well below its competitors. LS loaded with features. Great engine. Interior ergonomics are comical. Surprisingly little thought put into switchology. Can't see speedo behind wheel. I just can't get comfortable in this car, as nice as it appears. Poor city mileage. Troublesome brakes. Have redone front brakes …

2004 Mitsubishi Diamante LS 4dr Sedan (3.5L 6cyl 4A)

Three-time Mitsubishi product owner (Eclipse '91, Expo '94 and Diamante) - all exceptional value for the expectation. Ran the first two into the ground. Bought this used with 16,000 miles, and I have no reason to suspect that this model will not make the grade. Interior has a couple of flaws - seams splitting on back bench and carpet pullaways, and sound system seems to have been …
