Cheetah, You have a very nice car, but your pictures are total crap. eBay auto auctions are a competition. Look at your competition (the cars that are not as nice, but are likely to sell for more). Make your pictures at least as nice as theirs.
Get your car out of the garage and into some decent lighting. Full car from all sides. A pleasant, but non-distracting background. Show it off. You really are going to sell yourself short with what you have.
