Is Apple still replacing top cases?

I had a 2006 CD MB and the last time I had it replaced was in 2012. Is Apple still doing this when they are cracked?

There's a 2007 on Craigslist right now along with a MM that I'm interested in. He asked for offers... and I offered $100 for the MB. He said that, along with all the other junk he's throwing in with it, is only worth $65.

It has a 320GB HDD which I'm sure I can find a good use for it.

 

He sent me a picture of it and it actually doesn't look that bad... but has stickers all over the place.

Any idea what I can do with it or what it'd be worth? It's a mid-2007 MacBook, I'm assuming. He said it came with Tiger. I don't think I have a need for it...
