Hi all, I've browsed through this forum whenever I had a travel related question for years now, and it's never disappointed.

So I'm getting married in July and we're going on a 2+ week honeymoon to Europe. We're flying into Munich, renting a car and basically visiting a few friends/family in between the actual honeymoon. Long story short, I currently have a reservation for a BMW M440 convertible, but I'm trying to figure out what they have in their fleet. Cost isn't that major of a concern, within reason. The current reservation I have is a bit over $2k.
I was looking at the Porsche 911, but not only is that around $5k, but the mileage restriction would likely screw me. Does anyone know if they have any Porsche Caymans in their fleet? S4 convertibles? Any thoughts would be appreciated.
BMW is a nice car and all, but we have a 5 series at home, so I'd rather try out something different.
