For a game that touts itself as being "The Real Driving Simulator", I don't think there's a place for any imaginary car in the game, period. If it's been built and run in the real world, certainly, otherwise get it gone.
And while I'm at it, let's lose all those useless ancient rides as well. Kubelwagon? Really? What's the point in having that in my garage?
PD needs to punch in some real world data and include more actual cars. Notice that Oldsmobile was excluded? Lincoln? There's just so many actual cars out there that weren't included in the game that could be, why bother with the imaginary crap?
