I just recently went to spain for a week long break and the wife, me and 2 kids took 2 back packs both 10kg each and 2 x 25kg size suitcase in the boot was a squeeze but they fitted
The boot easily fits the weekly shopping ive attached a photo from easter, the eggs were the large type so it might give you an idea of depth
If you need any more info on any aspect of the car just shout
The power and comfort of the car is well worth the small boot
We averaged 33 mpg doing the 3 and half hour journey from house to airport and back
