Hi ! I’m looking to rent an A Klasse Mercedes Benz or GLA model , most common rental companies only rent within a category, but I’m looking for renting only merecedes brand. Is that possible or am I dreaming ?

i tried through Mercedes mieten in Germany, but after 3 weeks of trying to get them to understand me vía email and phone, I’ve just given up.

So I would really appreciate any input on my question. Thanks in advance !
