Saturn 25 - take out LL & 1 SD, install Laser and switch with Vulcan; armor: F50 R35 L35 B40 T19 U20; 6595 lbs., $24,900
Design Notes: See my rant about Station Wagons. This is the first of my wagons and it's dated not only because I don't design wagons for duels anymore, but who needs Light Lasers anymore (which requires another rant).
