Hi Kristin,
I'm brand new to this forum, but not brand new to ebay. I looked at your ad. The main thing that comes to mind is why is there no warranty? Escalade is not even 2 years old and has only 11,000 miles? Shouldn't there be a balance of the factory warranty remaining?
If you look at all the SUVs (large ones) on ebay, they are all going for a lot less than they did a few months ago when gas was cheaper. I'm not sure if that's the reason, but it's just my guess. Also, you get a higher price if you sell your vehicle in the spring, after tax time. Now isn't the right time to sell, right before Christmas and with the cold and snowy weather coming. Who would want to chance getting rust on that baby? Or driving on slick roads, possibly getting hit by someone not proficient at driving in snow (was that politically correct way to put it?). Now is definitely the right time to buy - I could buy a low-mile 2004 DeVille for under $20K.
Otherwise, I like your auction page and you make everything clear. Nice ride, by the way. I hope my opinion helps, but it is really only my opinion.
Good luck,
Deb
