Is it possible to secure a specific model? And question about upgrade
 

Next July I'll be in holidays in Germany. I booked trough Sixt website a CPMR class (bmw 1 series, golf GTI, mercedes A class) and request sat-nav, pickup is from Cologne-Deutz that seem the closest to my hotel.

In the reservation remarks I write about my preference about the BMW, Is there any other thing that I could do to secure this model, I prefer BMW for the RWD and beacuse I know very well this car. And is there any possibility to secure, at least, a 118i (if available 118i or 125i). If there's any fee applicable to my request I don't mind to pay for it.

The second question, first I'm looking for a SLK or Z4 (PTMR class), but I only see it with kilometer restriction and is not enough for my tryp, It's possible to book this class with unlimited mileage or with higher limit?

Thanks.

Regards.
Iker

All questions: no

ok, thanks.

i'll cross my fingers to get the BMW...
