Shall sell or give my car?

Q : Shall sell or give my car?
I have a 1999 Nissan Maxima with 220,000 miles on it. Shooting break calipers and they want $ 300 + to fix. I just want to get rid of the car. Money is a problem now that I am a nursing student then how I could make a donation and amortized over taxes? Kelley Blue Book is about $ 2,500. Or should I try to sell it?
A : When you donate a car that put the indicative cars. So if you value your car at $ 3000, you get a tax credit of $ 3,000! Sell ​​only make like $ 1000 or more.
