Always remember one thing about cars, unless you're looking for a super rare one.. ANOTHER ONE WILL ALWAYS COME ALONG AND IT ALWAYS DOES (especially in a down economy)!
Also, Are you sure you want a black car? They look great as soon as they're washed or polished but show dust and dirt rather quickly. Also, expect the interior temperature of your vehicle to be much hotter in hot weather than a lighter colored car. And, they also show dings and body imperfections much more prominently. Just a word of advice.
