 My 2000 Mitsubishi Diamante has been extremely reliable and fun to drive.  I've always liked the styling of the Diamantes, and you get a really nice car for a reasonable price.  The only disadvantages I've observed are their poor resale value, and some components could be of higher quality.  For example, I was told at 38,000 miles that my struts were going to need to be replaced soon.  (However, I haven't replaced them, and it still rides fine.)  The other quality issues were more cosmetic in nature, like a trim piece that peeled.
