Well Ashe and hts will be very happy to note that out of an 11 car round-up of sports-sedans by Road & Track, the G35 came out on top of our beloved 330i.
Fear not though, because almost every reviewer chose the 330 as the best car of the bunch. Before tallying up the points for "price" the 3er had an 8 point lead (308 to 300 i think) which included everything else from aesthetics to handling to ergonomics, etc. Of note, the 330 came in as the leader in all performance categories, and tied the G35 for 1/4 mile (despite the 50hp difference). After adding the price points though (200 for the g35 for being the cheapest, and 182 for the 330 which came in $7500 more), the G35 came out on top.
The entire article was full of praise for the bimmer, and qualifications for why the G35 won (and it was not because it was the BEST sports sedan in the mix). We all know this means nothing, and it all depends on whether or not you'od rather spend the $7500 on the 330 (obviously most of us would), but as always comptetion is a good thing and will only make our options in the future better.
