I wasn't sure about 535i, but I know when I made reservations in Sixt.de, they did show 535d, but when I got there, they told me they never had one. That was both MUC and FRA. They always gave me the 520d (downgrade) and I rarely saw 530d on the lot. I never saw 535d.
I know I have seen 523i and 530i. The U.S. has 535i (with 300 hp).
