Re: Spider Luggage Space
Depends on how tall you are - I guess you could get the medium sized suitcase in the boot OK and fit the two smaller squashy bags behind the seats - there is lots of room there but again... dependant on the size of these bags, you will either need to have the seat slightly forward or tilted more upright or both.
Alternatively, put the medium sized suitcase behind the seats and squash everything else in the boot. The Brera boot is bigger of course - and it has folding back seats that help!
Do you have a passenger? Rather than try to get stuff in the passenger footwell, it is better IMO to move the seat forward and use the space behind.
Finally - have you thought of a boot mounted luggage rack? They must exist.
