Maybe run a contest with your followers and ask them to choose a name or suggest a name, etc. Get them to get share with their friends,. Like the winner gets a profile mention or shoutout, t-shirt with your new profile name, something relatively inexpensive to create, but of value.
This way you can create buzz for your page launch, pick a name, get you followers involved and maybe their friends.
If your campaign goes better than expected approach a sponsor in the classcicars or vintagecars niche for tickets to a car show or something as prize in a contest/draw.

Good Luck …
