Thanks everyone. Great to see so many opinions.
I did email both garages (Skoda and VW). I received a reply from Skoda, arranged a test drive and indeed had the said test drive without hearing a thing from VW.
The test drive was just us and lasted about an hour. I already have the ID3 so the look felt familiar. The biggest difference is the size of the boot.
In the boot went my folding Quickie Xenon 2 with wheels attached, and then Mother In Laws rollator and there was a bit of room to spare.
I love the wee ID3 and would heartily recommend it if you usually travel two up. We have done some long journeys with ease and the car is fully loaded with everything VW could find in the parts bin. Some of these toys I shall miss but the boot space top trumps everything. Might even fit the MIL in there as well!!
