Study your nearest taxi rank, pick out the best car and negotiate with the taxi driver to do your escorting on the big day. We did it at our wedding (used the then Jury's taxi rank in Ballsbridge). The driver (Merc 500) was a character - he wore a tux and did up the car with ribbon etc. It saved us some money and added to the stories of the day!
