Do NOT let us catch you owning one that is desired for another Race. The Faculty will automatically destroy your vehicle and you will not be allowed another one. If you need the Gas Station, wander around until you find it. It isn't that difficult to get to. Cars and Sacuers can move as fast as they like with a couple of general rules.
Saucers are faster then the average car.
Cars with souped up Engines equal a normal sacuer but not one with a souped up hyperdrive. It's for RP purposes. If the Faculty deems you are moving way to fast, the Cops will pounce on you. Speeding Tickets are 35 bucks apiece.
