I rent with Sixt every year when I go to Florida as I find their range of cars miles better then any other hire company, for the last 2 years I've reserved the bmw x7 and on arrival I got what I've booked.
Made my booking again for this year for June time and I've noticed their isn't any bmw x7 showing for hire on there app or website. I always check on the run up to my holiday as the prices sometimes drop. Could it be they are no longer hiring out x7's hence no longer showing.
