Our last 2 Motability vehicles have been a Ford Galaxy (61 plate Titanium X 2 litre diesel, 66 plate Titanium X 2 litre Ecoboost with 240bhp).
We looked at every other 7 seater available (Pug 3008, Seat Alhambra, Ford C-Max, S-Max & VW Sharan to name a few), but nothing had the same power or level of equipment as the Galaxy. We paid £3500 advance premium, including the Family pack (rear window blinds, 240V socket, Isofix in all 3 middle row seats).
Our 3 year lease ends October this year, but since our mileage will be under 15k, we will probably extend the lease to 5 years.
We will certainly consider the Skoda Kodiaq and 5008, but I doubt they'll have an engine option as good as the Ecoboost.
