Thinking about parting ways with my A body, give me opinions on what I should ask for it.

if you need the money sell it, its just a car. if you don't need the money don't sell it as UDUST81 says, you might want it in the future. Park it for 3-6 months, if you don't miss it then its time to let someone else enjoy it. I agree with UDUST81, 8-10K.
