Please do share with us your source on Mercedes telling PD to not include a detailed interior. So far, all the evidence suggests that the interior is done and ready to be modelled by PD. You know, that's their job. Not MB's.
I don't know what is most sad. That people will defend PD's pathetic design decisions and pure incompetence, or that PD still haven't upped their standard.
But hey. They've only had a grand total of 8 years to do things like model cars and traks for GT6...
On another note. If the car isn't done, then why on earth would they include it? They certainly don't seem to be in a rush to include the sound changes (another thing they've had countless years to work on), or the course maker that we've yet to get details about. How the hell this company is still in business is amazing, now that I think about it.
