It doesn't come with a car adapter, but go on ebay and they sell them cheap. Because of the size of the screen it was hard to find a decent case because most of them will only accomidate barely 8 inches. I went to Circuit City and they sell a bag called "Targus" and this bag will do the trick. I even brought my Toshiba 2500 into the store and sized it up. Plus the bag holds extra dvd's and cables, really a good buy and I recommend picking it up because this one switches from a back-of-chair viewing to a suspension between the two front seats.
If you can get your hands on this please do so. I did my homework on portable dvd players for over 6 months and I am proud to say I know I couldn't have done any better.
Not cheap - but I don't mind paying if I get results and the SDP2500 DELIVERS.
Only dissatisfaction is that some of the many, many functions are only available with the remote control. You can certainly do all the basics without the remote - but need it to get fancy.
We love the SDP2500, and never, never travel without it.
