Thanks for the feedback. I made a Sixt reservation at the central MB agency, near hbf - I assume this gives a decent chance of getting something I seek. I booked an LDAR for 9 days - I'd like to get the new E350 blue efficiency, but if they didn't have one and upgraded me, I wouldn't cry

I forgot to check the 'diesel' preference on the form - I assume it is not a problem to simply ask for this upon arrival.

I hope my thread isn't out of place here...this is the only venue I could find to discuss what cars might be available.
