if you can afford to wait for it to go, I would sell it privately.
I had a 2002 V8 Statesman that had just done 90,000k's, was in PERFECT condition (we were second owners, the previous owner was a fam friend who is very fussy with her car, and so am I!) and we got a 12,000 trade for it (Paid 21,000 for it, with 60000k's on the clock and had it for just over 2 years) When it was easily worth at least 16,000!
