There are no D class porsche, sorry. Boxster s is an E class ! BMW E36 ? it is an E Class too There are not many D class in this game ! The only D class i found i the game, untill now are the Lotus Esprit V8 wich was already in the original game and the Aston Martin DBS wich replace the DB9 wich was in the original game and BMW M5 E60 and M5 E39 and 1 or 2 other cars like the Ruf RK Spyder wich was already in the original game ! And i don't like theses cars very much ! By the way, it is always you that choose the Class of the cars.
