Personally, it is necessary. Many years later, you may have forgotten what you said at the wedding, but you will definitely remember what happened at the wedding reception. Why do you need a wedding car to pick up relatives when you get married? Because we want to make the happy time better.
Of course, if you think the wedding car fleet is too expensive, the average price will be around 2000-3000. Six Mercedes-Benz or BMW teams, you can use brains, bicycles, sedan chairs or motorcycles, but sedan chairs and motorcycles should not be cheaper than group wedding cars.
