Booked: FDAR BMW 3 Series automatic or equivalent
Received: PDAR BMW 520d xDrive
Not too great specs... Sport Line, Navigation Professional, digital dials, 19" rims, digital key and that's it. But it was cheap, clean and great service.
I remember a charged "upgrade" last year (January 2019) that was quite disappointing...

Booked: PWAR BMW 520 Touring or similar
Received: LWAR Audi A6 Allroad 3.0 TDI
Extra 30 EUR per day. Madness for an old model A6. At least it was pretty well specced: Leather/alcantara combo, power seats, navigation, heated front & rear seats, bose sound system, 4-zone climate and many more. But 30 EUR per day for an old model is just nuts. I could have gotten an S350L for the same price had I booked it online.
