Since most of my favorite items are now out of the system (oh Manhunter, where did you go?) I would have to go with:
Ingram Smartgun X - recoil compensated and suppressed? What not to like!
Savalette Guardian w/gas vent III
Mortimer Great Coats, Ballistic masks
Retractable Spurs, Cyberarm Gyromounts, Smartlink
Suzuki Mirage (Yamaha Rapier, why did they scrap you too?)
Saab Dynamit
Appaloosa Light Scout Vehicle
