The driver seat has worn a bit.
Heater on driver seat was not hot when I bought it, but still under warranty, so I got a new seat bottom for free.
The check engine light came on a few days after purchase, I took the car to the dealership, and they ordered the wrong part. Not just once, but 3 times, and when they got it right my warranty was up, and I was frustrated.
Now the check engine light is intermittent, however, the car is still reliable. "Check engine" lights are only for smog stuff (generally).
Finally, compared to 4 bangers out there, it is a bit heavy on the gas.
This car got me from Northern California to Illinois, Illinois to South Florida, South Florida to Arizona, and Arizona back to Northern California, all in one trip, and did not have any problems!
I LOVE MY CAR and I LOVE TO DRIVE! It's even fun to say "Diamante", try it. I Love its speed, when you give it gas it does not hesitate, even up hills. It takes corners very well. When you put all the windows half way down it feels like you are in a Picasso work of art because they go down abnormally. It's performance is sporty, yet I can pick up my family from the airport. I got limo tint on the back windows, windshield bar, sun roof, and 20% up front, now it has a well defined business look.
I agree with you in the fact that it is fun to say Diamante and it is a very classy and comfortable car. However, it is of best advice to have that "check engine" light checked. Smog and emissions is only one thing this light tells you about. It also goes ON when vital functions go wrong, like oil pressure, fuel pressure, lean mixture, misfiring, and sensors gone bad. All this can affect the power and economy of the car, and most importantly it affects it's durability. So have that light checked, it is not expensive and you owe it to your car, since it has been good to you.
