I bought a used 2004 last August with 35k on it. It now has 50k on it and at 48k the alternator went. I replaced it and it cost me $600 with labor. BTW the labor was only $100 dollars to give you and idea of the price parts can run you. Now with that being said I love the car to this day. Even though I still think the alternator should have lasted to 100,000 miles but maybe I got a bad one. These things happen. If the car is in good shape with low miles chances are you will have no to little issues with it. If anyone else on this forum has had any issues I haven't seen any major ones.

Good Luck.
