Ford Transit(Hertz) or Fiat Ducato(Avis)
 

We plan to travel around Italy and look for the 9 passenger van.
From Hertz, Ford Transit Combi 300S 2.2 could be available.
From Avis, FIat Ducato is available.

Since we have a lot of luggage with 7 adult passengers, the luggage space at the back of the seats is important.

Do you know which is better for us?

Also, they always say one particular model or similar.
IS there any way they can guarantee the specific model?
If we rent it but they change the model to less luggage space van, we can not travel with our luggage.

Thanks

Most of the 9 seater vehicles in europe are exactly the same size, I'd call the local office and ask them if they have a transit with a long wheel base i.e. a 13 seater that has the 4 fold away seats at the back.
