I don't think the 328i is an inferior car. If it's a choice between a loaded 328i and a stripper 335i, I'd go with the 328 all the away. Even though the 335i is much more powerful, I'd doubt you'd notice the difference in everyday driving. In my car, the only time I pass 4000 rpm is when I'm stop light drag racing, passing on the freeway, or driving on a canyon road. Everyday the 328 has more than enough power.
