I purchased my 2000 Mitsubishi Diamante in Dec. 2003. I did a lot of online research before purchasing and found that most of the people complain about its fast depreciation, but praise reliability of the car. I was looking for a good used car, so fast depreciation was a good news. Why pay $36,000 for a new, when you can get a great used car for $12,000? So, I found a Diamante with … 55,000 miles online and drove it home. For two years that I owned this car I just did regular maitainance (oil, transmission fluid, brakes, put new set of tires). I had no problem with transmission, it shifts perfectly. I didn't have any problems with the heat-core either. I spent only $480 in maintainance to keep this car in excellent shape for two years.
