Unless you need something immediately, your best bet is to put an order together and get it from your favorite Delorean vendor. In many cases it works out cheaper and you KNOW the parts they sell you will fit and work. Obviously tires do not have to be purchased from a Delorean vendor but in many cases parts you need just aren't available locally anymore. Wiper blades are bought based on the length but nowadays you will have a hard time finding refills, most stores only sell the newer beam type blades and they won't fit unless you change the blade holder too. That is expensive since a refill only costs a couple of bucks each on e-bay.
