What alternatives should I consider to a used Seat Leon estate?
If the Leon ST doesn’t quite offer enough space then it’s worth looking at the contemporary 2013-2020 version of the Skoda Octavia Estate as an alternative. Not only does it have a roomier boot but passengers can also stretch out slightly more. Just be aware that while running costs will be similar to the Leon ST’s, the Skoda is not as enjoyable to drive.
For something that matches the Seat for driving enjoyment you could consider the Ford Focus Estate, but be aware that its boot is significantly smaller than almost anything else in this class.
