I've had my G8 GT for two months (as of tomorrow) and so far I have had three people instigate (or try to instigate) a street race with me in it. Two of them have been Mustangs!
So, G8 owners, have you intimidated anyone on the road? I find that Mustang owners in general seem to get really defensive around the G8. Funny stuff.
Apparently this car has some street cred, at least in my area.
