You don't need antimatter. Which is good because studies have shown antimatter to be dangerous to the environment,and also to be one of the carcinogens found in cigarettes.
Theoretically, you would need a Delorean capable of acheiving the speed of 88 miles per hour. Unfortunately once you even manage to locate a Delorean for sale at a reasonable price and then equip it with the nuclear reactor, flux capacitor, and necessary computer equipment the vehicle would no longer be capable of even leaving your carport.
