Another good comparison review, Mike. Although a big fan of hot hatches, none of these vehicles really floats my boat- I just can't get over the "form over function" nature of all three. Personally, I think I'd look at a FWD Juke for a "value" funky FWD tubo- about $23K all-in right now IIRC (with incentives). Interior may not be as nice the Veloster turbo, but likely more fun (and probably a lot more usable year round with the increased ground clearance, although the cargo area is similarly small).
If going to step-up to the "big league" of FWD hot hatches, the only reason I could see anyone taking the Beatle over the GTI or the Focus ST is style. But price is no better, performance is slightly worse, and practicality is significantly worse. Good on VW for continuing to improve the model though.
