Hi girls, I'm back after a little hiatus! Wedding is less than a year away (hit the 1 year mark last week)

I have a question regarding the best way for transportation on my wedding day.. We're gathering quotes from different limo services around the area, but not sure on how many cars to get!!
For my Dad & I to go to the church, I'm looking at an antique car-- like a Rolls Royce or something (depending on the price, which I'm sure wont be cheap) Then after the ceremony, my FI & I would ride to the reception in that same car obviously.
I only have 4 bridesmaids, so was thinking of doing a smaller-sized limo for them. But my question is, typically, how the groomsmen & groom get to the church!? It seems like such a silly question but I want to avoid getting 3 cars, because price-wise that would be a lot.
Thoughts? Thank you in advance!
