Haven't got time to trawl through and see if this has been posted:
MINI Cooper S '07 - in interior view, the rev counter is out of sync with the gauge provided by the game, so whilst hitting the limiter at 7k rpm, the dashboard only shows 6k rpm, with some way before the red line. 6k actual is shown as 5k, but idle is about right.
Also, despite having a full tank, the dashboard shows only 3 lights of the fuel gauge lit up (more lit up = more fuel) - although I realise that moving fuel gauges aren't included in the game.
