Really one needs to test drive the cars, not just sit in them and see how they actually work for you and most importantly drive. Often though the model you want is not the one you test drive but gives you some idea. Every car I had on the scheme ticked all my boxes but was the best feeling and practical car on my shortlist. Seems like you got your shortlist together and for me the test drive would be the deciding factor.
After all you then got to drive it for 3 years minimum and the more money in ap you spend, the more important it is imo to get the decision right, and not regret it.
Fuuny thing also is that the dealers will get the same fee even if the cars more in ap so some might not be as welcoming as others and that’s another factor to consider, although that also doesn’t mean it translates to good aftercare and service.
I personally wouldn’t get another car that didn’t have seperate heater controls or that virtually everything was controlled by the infotainment screen or voice as I don’t really want to talk to the car and if you have an accent would it understand you? By the time you done that all, one could of demisted the front windscreen already. No matter which car we’ve had that’s always been an issue and happens regularly.
