Thanks for the info, guys! I am trying to finalize a deal on the car. It only has 19,300 miles on it and is 2.5 years old (only 5 months of warranty left). I drove the V8, and that is a smoother engine, but it is also lacking a stick. I kind of miss the stick I had in the CSVT and wanted to get it in the LS for the fun factor. The auto in my Sable is so boring. :-)
If I close on this car, I'll post back a more detailed response. But it is quicker than an auto V6. Plus, if you follow the auto mags you'll know that Ford has had trouble with the ATX in the V8 LS.
