I just wanted to share this in case it can help someone else; after many many many hours looking for a travel system small enough to fit in the MINI One boot but with big enough wheels to go off-road with the dogs...we have found one! I have high standards and wanted it all and found it in Phil and Ted's Mod; fits perfectly, and the seat unit folds right up with it (so is in the boot too! No extra space required!) It fits either standing up or sideways, though standing up needs the parcel shelf taken out. It's a great fit and can probably fit a Tesco bag in with it too. It's a fantastic pram, lightweight, sturdy, stylish and price includes the bassinet so is a steal. It's a NZ company so not too well known in the UK and we couldn't find any to try but we took a punt and very happy we did!
