Ideas for vehicles for prom?

So, on the 1st of July it's my prom. It's all been a bit of mess vehicle wise, we were origanlly going in a fire engine but that got cancelled, then we were going in a limo but people started dropping out so that got cancelled. There is now eight of us and we have no idea how to get there. We want to make an entrance, but at the same time we just want a vehicle that is cheap. Anyone got any suggestions? :) <3
