Hrm... in no particular order some that come to mind:
-Back in the day I really liked the C&C Angel IR3, with the crazy cutlass trigger guard.
-DC Viking with full FSP milling (especially with Stormtrooper anno)
-Deadlywind Dallara body is on my pipe-dream list
-X-Mag in general, but the Armada-X stands out to me as a masterful evolution
-Atomix Intimidator was cool, but more so since it was from a local field/team (I miss that field...)
-Westwood Autococker - out of this world a the time
-Spearhead Autococker - so mean lookin!
