My nod goes to the SVT FOcus simply because it has less mileage, still within warranty, and has nice factory wheels and HIDs (I think that one has the Euro package right?) THat's just for a daily driver.
The CSVT has A TON of options available from the aftermarket, and it's all really cheap as well. . .you'll have a balls-to-the-walls fun car for sure. . .
But, like I said, it's about the mileage and how Ford's in general hold up. . .
