Sixt has pretty much revealed their Summer 2014 “Luxury” fleet. See separate post.
I have been looking forward to see new M3 (F80) and M4 (F82) in their summer 2014 fleet. And the good news is that Sixt will be adding both to their 2014 fleet. Bad news is that cars won’t be available until mid August beginning of September.
I’m not aware that any car rental agency in Germany (or elsewhere) has new BMW M3 / M4 in their fleet yet. There is still hope that new M3 / M4 will make to BMW On Demand – BMW Welt Munich fleet for this summer.
UPDATE (6.5.2014 13:00 CET): According BMW On Demand M3 / M4 will join to their fleet July/August (2014) timeframe.
