Auto used car

Im looking for a long term vehicle that will last me 10+ years after my mk7 golf match edition 2016 gets sold in a year or two.

I'm thinking one if the following:

BMW 3 Estate, Corolla estate, passat saloon/estate, E class saloon, Superb hatchback, octavia hatchback

I really want a saloon with a boot much bigger than my current mk7 golf 2016 and bigger rear seat space for baby car seat and passengers.

Features I have to have:

• ACC
• Heated seats
• Front AND rear parking sensors
• under 70k mileage
• Atleast 2017 plate (will accept 2016 if it has it all).
• Boot space 400L plus with seats up, preferably as close to 500 as possible.

My top 2 choices so far are superb and passat saloon but not sure if the Autos are reliable. I know the Corolla estate Auto is smooth and has what I want as I've driven it but it seems to be out of my budget.
