I have a feeling that there is going to be some racing for "pinks" with the gift system.
Example:
GTP'er - I am a much better driver than you.
Someone else - No, I am a much better driver than you.
GTP'er - I'll race you for pink slips.
Someone else - Ok, name the time, place, and car.
GTP'er - Viper ACR, 5 lap maximum, Nurburgring, best lap time wins.
Someone else - Ok, deal, which car are you putting up?
GTP'er - Fully modded R35 GT-R. Which car you putting up?
Someone else - Stock Enzo.
GTP'er - Ok, that works. See you out there.
It would go something like ^ that, but it would probably need to be a friendly rivalry, or with someone that you really trust, because if you put up one of your hard earned cars, then you want the other person to be honest, and if they loose, to actually "gift" you the car they said they would.
