Uh? Regular employees of a company with million-dollar cars? Quite incredible claim. Even Google pays what, half a million or so to top engineers from what I read left and right? You don't drive million dollar cars on a salary (any salary).
Lamborghini Murcielago, 2010, premiered at $400,000 to $600,000.
However, when people are talking about a million dollar car they're most likely remembering the McLaren F1 which sold for $970,000 back in 1998.
