Let me take a second to pass on some valuable tips from other successful vehicle sellers.
Title - at a minimum make sure to include the Year, Make and Model. If you still have space, use a descriptive hook to encourage the eBay audience to look at your listing.
Description - Put as much information in about the vehicle as possible (you have lots of space, so don't worry about running out!). Include features and options on the car, specify if you can provide a service history and any other important information that a buyer would want to know.
Pictures - Provide a total "walk-around" of the car. Take pictures of all sides, the drivers seat, dash board, odometer, rear seats, trunk and tires. Additionally, try to include pictures of any damage on the vehicle. This way, any potential buyers will have a much better idea of the vehicles condition. Basically, the more pictures the better.
One last note, make sure to wash the vehicle before taking any pictures
