Just returned from a two week rental at SIXT Miami and got a new Cadillac Escalade ESV. I rented between April 17th and May 1st, and at both pickup and return there were plenty of Cadillacs available (4+ in the small lot). Upon pickup I was offered the choice between a Volvo XC90 and the Cadillac.

When returning I asked if this was uncommon for the XFAR but according to the sixt employee the continuously have a lot of Cadillacs in this class.
