You said it was 16k on page 2, now it's 17k again. Which is it?
Not trying to rip your thread, but take a look at some prices of other 99's for sale on the board. I realize your's has great mileage, and is probably in a little better condition than most...but the majority of "us" aren't going to pay an extra 5-7k for an 8 year old car with lower mileage.
Good luck to you, may want to try ebay and autotrader, just to see what you can get as offers.
