I'm going to go ahead and make a bold prediction about the DLC.
The Prius Touring Car will be by far the most fun car to drive in the whole pack. The other cars look nice, but sometimes the cars that are just a tad bit slower, but they handle really well are the best. A tad bit slower is probably an understatement at best in this situation, but I still think it's going to be a ton of fun.
Here is the new cockpit view, not that great for some of the standards. Especially for ones where they are all black.
Yeah, they definitely went for function over form with the standard interiors. There was probably a loud outcry from people who only race in cockpit view just for the realistic perspective of being behind the wheel, so this is probably aimed at just them.
It really would have been crazy to try to model every standard interior + any cars you could import from GT PSP (also standard cars).
Lots of E-Rage around the internet about an hour ago, but the GT5 DLC update is working now. After the purchase (where it'll only show the gift car and theme), you start up GT5 and hit the downloaded content button on the right side of the main menu.
Aforementioned rage was due to the game not immediately recognizing the purchases for anyone immediately when the update came out.
