Been trading some extremely expensive cars in Gran Turismo 5 recently with a few members on GT Planet. Seeing as the servers have been swallowing some cars into the ether recently it's serious internet business to do this!
It takes 40 minutes to grind 1,000,000 credits and some cars are 5,000,000+ so these things can't be replaced too quickly if you get scammed or lose your car!
My last trade was giving away my 4,500,000 Formula Gran Turismo for a 5,800,000 Bentley Speed 8. :O You can gauge the sort of risk involved when you may lose your car to a stranger!
The game should have a secure middleman service for these trades rather than having to place actual trust in an individual.
Anyways...
Still waiting for Red Dead to turn up even though it should have been here yesterday.
