I applaud Lexus with their first ever IS-F and also the LF-A cars but IMO it will be at least another 5 years before Lexus can keep up with Mercedes/BMW in terms of producing performance edition cars in each of their lineups.

It seems Mercedes has an AMG version for every model and BMW is the same with their M-line. Lexus only has ONE F-model within realistic budgets and their production of sport cars is still a backseat thing if you ask me. It will be years before we see it but I'll be the first to admit it would be cool to get a LX570 or even LS in an F-version!
