[csx4910]

If I can chip in here, I have owned both in the last year. A SPF with a 620 HP Ford racing 514 with a automatic and a Csx with a Roush 511 with 600 hp. I prefer the 5 speed but the auto was just as much fun to drive and could spin the tires in the first 3 gears without a problem. The auto was much easier to drive, particularly at lower speeds. My wife could drive the SPF with 600+ hp easliy without being afriad of it but refused to try the csx after one drive. I had no problems at all with the downshifting of the auto. My wife kinda wanted to keep the SPF so she could drive it some but I couldn't afford to keep both toys.
