Never drove Fiat before. In 2 weeks I will get a rental car as the following at MXP:

(Y) Fiat 500L Automatic or Similar
Compact, 4-5 Door, Automatic, Air
5 Passengers
1 Large Suitcase, 2 Small Suitcases
Automatic Transmission
Air Conditioning
59 miles/gallon or better
105 CO2 emmissions

My concern is that I will bring one large suitcase and two medium size suitcases (carry on size: 20" x 14" x9"). The "large" suitcase is something like the 29" Samsonite: with 29" x 20" x 12" (expanded) dimension. I am not sure if mine "large" suitcase is the same as the spec mentioned in the Hertz rental car description...

Anyone with driving experience of Fiat 500L can clarify a little for me? Thanks in advance.
