Ill tell you what, heres my honest opinion.
your car looks real nice, and real clean.
I think it might even be worth $10k.
BUT, the pictures youve posted are complete crap.
they are so small, and low detail, i wouldnt even bother to send a message if it was $3k
Buy/borrow a real nice digital camera. at LEAST 1 megapixel.
Take specific pictures.
Pictures of how clean the engine is. the interior. dash, seats, back.
pictures of the rims, all the mods, the stereo equipment. how glossy/clean the paint is.
Then. you will get major feedback.
Host the pictures on imageshack.com or photobucket.com if you have to.
even try listing it on ebay. if you dont like how its going, cancel the auction.
but remember. all the high bids happen within the last ~60 seconds of the auction. so try a buy it now or something
But definately. GET BETTER PICTURES
