I can't speak for your vehicle, or any VX at the mileage, but since I am one of the most recent VX buyers on this forum I would be glad to share with you my purchase price, I just hope it doesn't depress you:
2001 Proton, 35K miles, front cladding damage and no back seat, most everything else in excellent condition, one owner, (Massachusettes):
Purchased on ebay for $8200 + $150 dealer fee = $8350
Shipping to Florida: $750
Tax/Tag/Title: $700
Replacement Back Seat incl shipping: $230 (I think)
So I'm in for nearly 10K before I start mods and what not.

Now, I know shipping isn't part of most peoples sale calculation, but you could sorta say I was willing to pay about 10K for a ready to drive low mileage VX.
