Analysis
What Problems Does the 2004 Mitsubishi Diamante Have?
While specific recalls for the 2004 model year might be limited, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for any outstanding recalls related to safety or emissions. Over the long term, the Diamante's reliability can be questionable compared to competitors like Toyota or Honda. Parts availability might become increasingly difficult as the vehicle ages, leading to higher repair costs. Owners should pay close attention to routine maintenance and address any warning signs promptly to avoid major repairs.
How long will the 2004 Mitsubishi Diamante last?
Over time, weaknesses such as rust, transmission issues, and engine component failures may emerge. The availability of replacement parts can also become a concern, potentially shortening its lifespan. Regular oil changes, coolant flushes, and transmission servicing are crucial for maximizing its longevity.
What Technology & Safety Features are Included?
Driver-assistance features were limited compared to modern vehicles. Cruise control was a standard convenience. Safety features included standard anti-lock brakes (ABS) and front airbags. Side airbags were available as an option on some models.
While specific crash-test ratings for the 2004 Diamante are not readily available, it's important to note that safety standards have evolved significantly since then. Modern vehicles generally offer far superior safety technology. The absence of features like electronic stability control (ESC) and advanced driver-assistance systems (ADAS) makes it less safe than newer cars.
Optional features might have included a sunroof, leather upholstery (standard on LS), and upgraded wheels. The overall tech and safety features are basic by today's standards.

2004 Mitsubishi Diamante Prices and Market Value
The Diamante experienced substantial depreciation due to its age, brand perception, and concerns about reliability and parts availability. Factors affecting resale value include the vehicle's overall condition, maintenance history, mileage, and geographic location. Lower mileage and a well-documented service record will command a higher price, but it will still be a relatively inexpensive vehicle.

How Does the 2004 Mitsubishi Diamante Compare to Other Passenger Sedan?
However, the Diamante falls short in reliability compared to the Toyota Avalon and Honda Accord, which have consistently better reliability ratings. The Nissan Maxima offers a sportier driving experience, while the Avalon provides a more refined and comfortable ride.
If reliability is a primary concern, the Toyota Avalon or Honda Accord are better alternatives. If a sportier driving experience is desired, the Nissan Maxima is a good choice. The Diamante is best suited for those prioritizing affordability and unique styling over long-term reliability and fuel efficiency. A Buick LeSabre might also be a good alternative for someone prioritizing comfort and value.

Final Verdict: Is the 2004 Mitsubishi Diamante a Good Passenger Sedan?
It's crucial to have a pre-purchase inspection performed by a trusted mechanic to assess its overall condition. Only purchase if the price reflects its potential risks and if you are comfortable with potentially higher repair bills. Look for examples with comprehensive service records.

Comfortable and fast.Great car to drive but parts can be a bit lacking to find. My problem is that I didn't look at what I could NOT buy for it due to the single year of mfg in the USA. I have purchased parts from Japan, China, and Australia(they made the car for 2 years and have a big fan base there). I would not recommend the car only for the parts issue. Aside from that, I love the car!

LOVE THIS CAR!!!This is my first car and I freaking LOVE it!!! It’s fast and got das basssssssss!!!! Car does not dissapoint, even for a 2004 this thing drives so smooth and fast, comfortable heated leather seats, and did I mention the sound system puts newer to shame!!!!!! Parts are hard asf to find lol, but it is reliable and I live for this car!! It’s def meant for road trips with how comfy these leather seats are. It’s 2019 and this car still passes up people on the highway and in town! Gas mpg could be better, but for the most part it gets 17 combined. I gotta get some stuff fixed on it so it should get better !! Love this car, don’t have any 2nd doubts about getting this car! I was gonna get a 2008 Mazda 6 but when I test drove them the Mazda couldn’t keep up, and the way this Car drives is as smooth as grand marquis, with the class of a Cadillac

A lot of everything... Especially fun!My first car was a Cadillac. I love big comfortable powerful cars that make you wish the trip will never end. When I was car shopping I would have loved another Cadillac like I had in my teens but they aren't always the most reliable or practical. Mine was a 1970 that was unbreakable and made of solid Detroit steel but gas was only $.99 a gallon then. At 5 MPG that would definitely break the bank not to mention they don't make parking spaces or garages that size anymore. Lol So I decided to compromise and went with the next best thing... The biggest reliable import I could find! Boy did I hit the nail on the head! This is probably one of the most unique, fun, fast, powerful, roomy, classy, reliable cars I have ever been in! I got a killer deal! I only paid $1,100 and it had 143,000 miles when I first bought it from the manager of a Mitsubishi dealership the beginning of this year! All the bells and whistles and very well maintained. Interior looked and smelled brand new. The reason it was so cheap is it was in a minor wreck not too long ago and they salvaged the title. You'd never know it was ever hit unless you lift up the carpet in the trunk and see where they welded. I get compliments on it all the time and people assume I paid $11,000! I've upgraded the stereo head unit to compliment the premium Infinity Sound System and plan to keep it as original and classy as possible. The only downside to a very rare car is if you have any issues or need any parts it could be a bit tricky. There's little to no repair videos on YouTube and I had to special order an air filter. Good thing it's reliable! I haven't tried looking for an oil filter yet. I'm keeping my fingers crossed! If you do need help online I'd recommend searching for Mitsubishi Magna. That's the Australian version. They're quite popular there and there's quite a bit more tutorials and info on the Magna.

Great car performanceIt runs really really well. The car has a lot of options for the interior so you can adjust seats and other stuff easily. The AC is ice cold and love the sunproof
