Should I buy a 2007 R/T?

Ok peoples,

I found a 2007 R/T with 7686 miles for $24999. It has the tow package, leather seats, rear dvd, and sunroof. So with that, I have two questions:
1. Is $24999 a good price.
2. Whats the difference between a 2007 R/T vs a 2008 R/T.

Thanks in advanced for your input.
