move the journey itself from car to train, rather from old car to new car.

Spot on, it's actually better to keep your existing car than to buy a new economical one that's better for the environment as we're only contributing to the increasing number of cars on the road and thee enviromental cost of building new cars.

I and my partner thought about getting a new car (she drive) that does slightly better mpg and better torque with much better safety feature but realised it's more economical to keep using our old Ford Fiesta from 2014 even if it mean we have to make several attempt to go up a 30% hill.

And the discussion should be how do we effect modal change- move the journey itself from car to train, rather from old car to new car.

If you're worried about putting off Daily Mail types, telling people to use bus/bike/train is far more alien than suggesting people buy more sensible cars, given how car dominated/dependent most of this country's built infrastructure is.
