Taurus SHO
Had one (Yamaha V-6), loved it. The Ford AOD transmission hated me, or the nitrous, or both.
If you ever get one, get a manual. I only got an auto because after 5 months of looking I couldn't find a 5-speed.
I've had a SHO V-8 block in my garage for about the past two years waiting to be turned into a coffee table... One day I'll get to it.
