As he sees a car is just for getting him from A to B and for much of its time its sitting idle just use the car allowance on taxi's?
My son now uses a taxi app where you put in your journey and companies bid for your business (can't remember what it is called) but he used it last week to get from Central London to North Surrey for £30 - quite how the driver/company made any profit beats me and he has never been let down, but if that way gets 2bears to the airport and back home......and he can do his homework on the way
And then just upgrade the the two 4WD oldies for that Freelander you mention and you can both use it for trundling around the lanes etc.
