hmmm . Seems like you may have TM problems with it DaimlerChrysler Vans LLC owns sprinter.com . But then again http://www.sprinter.net/ is a sprint car team database.
there wont be an TM issues with that. Sprinter is too common of a phrase/word. No dispute would win unless you are infringing on the product. I like the name $20-30 at wholesale. $xxx end user
