I never thought the day would arrive that I could exceed 4,500rpm, but I finally hit 1,200mi a couple days ago. The 323Ci is quite quick when shifting at 6,000rpm, but of course I've trained myself to "see" 4,500rpm as the redline, so I have to retrain myself for the new redline. And I haven't had an opportunity to exceed the high end speed safely, but I might one of these days. The removal of the 4,500rpm limit was more important to me.. Just had to share :).
