+1 for the SVT Focus. I have had a regular and an SVT Focus, and the SVT is definitely the Cadillac of Focii. Interior is superior, motor has more power, tranny is better, wheels/suspension are far superior. All in all, one of the most *fun* daily drivers I've ever owned! You could put that thing into corners at rates of speed that you really shouldn't have probably
For the blue one you're looking at; definitely have the mechanic bring it up to snuff for you. Realize that the SVT-F had some issues with low-idle bucking in the earlier production vehicles, but should be resolved with a simple TSB at Ford. Also, take a heat gun to the graphics to remove them, and then a little TLC with the wax and clay bar, replace the fog/head lamps & you're good to go man! You'll love the SVT-F over your regular Focus 1,000,000 times over dude.
