Does anyone know where I could rent a classic car for a day in North Jersey area? Something like a big boat of a convertible Caddy?

I'm getting married in May 2008. It's a small wedding, and we had an idea that it would be cool if her father drove her, her mom, and sister (maid of honor) to the wedding site in a classic car. Then the two of us could cruise off in it after the ceremony. Not looking for a muscle car, more of a classy boat.

Feel free to PM me or respond if you know of a place.
