hmm..well that was a nice little argument. Regarding the decision at hand, if you plan to "mod" it past about 250hp, you should consider the base model over the Sh because I guess ATTS can't handle it(or so I've heard). If you plan to keep it stock, or better yet autocross it stock, theSH is absolutely amazing.. it feels very balanced and unlike any other FWD.
good luck,
mike.
ps. fourth gens are worth considering too!
