I have seen a black VIP dream myvi in ss2 few times. That day also saw a VIP dream black iswara/saga sedan.
Just to share my personal opinion here. I think to have a VIP club, the compliances should be a bit more strict. Meaning, a kind of standard should be set. Perhaps something like really spanky body stylings, minimum of 18" rims, etc. At least it'll put some prestige to those who are able to meet the compliances to join the vip club. Of course, this would usually apply to those who are considered as hard core VIP modders. If not, well, a club to gather VIP enthusiasts would be nice too.
