I bought my ZS as a family car and it fits prams etc fine, well new buggy pram all in ones, you might not get an old siver line one in the boot! I bought a top box and roof bars for £100 and went to france with 3 adults and my daughter, all her stuff and ours for a week and still had room to bring 80 bottles of wine back.yeah to be honest, think i might keep it for what people are willing to buy it for it just aint worth selling, Looks like a top box rather than an estate!!! hahahah
Went up to Scotland in your ZT.........450 miles to a 65 litre tank of petrol there and likewise back (was reading 40mpg at one point)........we packed the pram and all our clothes and food and drink all in it including the moses basket too.......loads of room compared to the ZS but of course they are both cracking cars!ZS is quite a bit more practical than my IS200, the boot is much deeper and the seats fold down so better for prams/buggies etc.
The ZS is better than the ZT as well I think bootwise.
