Well Im thinking about trading in the mustang for a WS6 which one sounds better? Which is faster? Whats a 01 WS6 run in the 1/4 stock?

1996 Trans am WS6, Silver, Ram Air, 6spd, Short shifter, Full SLP exhaust, Vortech S-trim supercharger, 36k original miles for $13,900

So, which is faster? Which would you prefer? My only worrie is that the 96 is worth around 9 on KB so if I resale it in a year I dont wanan take a 4g loss...help me out!
