Daily driver? It couldn't be the S2000, as revving it to 6000+ at every green light would be tiresome. It couldn't be the TSX because...well, it just isn't enough. The Lexus could be okay, but not in this company. Plus, I just can't get myself to be a fan of Lexus (read: Scarsdale Lexus drivers are so damned rude). The CAT is amusing, but I need a bit more speed. Change to a lightweight front blade and it should be light enough....
That leaves the RX-8 and 350Z (as it should be). I think the RX-8 is a bit too soft for me (I can tolerate a harsh ride every day), although I'm sure the looks, engine, and handling are superior to the 350Z. And, ironically for me, that results in the 350Z as my choice. Its truck-like engine should be torquey enough, there's enough room for me, and it's the fastest of the group.
