Just to follow up on my thread - I recently completed a 9 day LCAR rental from FLL. Received a nice MB E350 at a fantastic rate. Sadly, the car developed a hiccup when I was all the way up in Jacksonville, and I had to take it back to Orlando for exchange - but received another nice E350 (and they had several other similar highlines on the lot) and hope to receive something for the hassle - I will rent from Sixt in FL again, even with the small glitch the price paid and car selection was excellent.
