Colonel Vessery [ion Cannon, Veteran Instincts, TIE/D, Engine Upgrade] (43)

Darth Vader [TIE/x1, Juke, Engine Upgrade, Advanced Targeting Computer] (36)

Scimitar Squadron Pilot [TIE Shuttle, Tactician, Rebel Captive(or Mara Jade)] (21)

The Crazy Taxi™ dishes out stress while Vader and Vass do work. The combination of Ion+Stress is the dream.

Tie/D Vessery has a lot of potential buddies to work with. ATC Vader is a great option I would be tempted to go for Mara Jade since your opponent does not get to avoid the Stress just by not shooting at the taxi. If you can load a ship with stress and Ion, it is going to be out of play for quite a while.

One alternative you may consider is trying to squeeze in Tomax with Crackshot + tactician. It's 6 more points with no mara/rc, so you have to make some tough choices. Maybe dropping EU on vessery and juke on vader. Both are nice, but they're still very potent without. Could even change Vader to adaptability. 0 points, and ps10 if you need it, or ps8 (so everyone is ps8)

Crazy Taxi™. LOVE IT!
