[Closed] Help me choose a car please

I haven't run a car privately for 17 years and the choice is bewildering, here are my main criteria:

Ideally something used but less than 3 years old
High mileage doesn't bother me as long as the car has been properly maintained
Must be able to seat 4 adults comfortably - 6/7 seats would be a bonus
Comfortable on long journeys, not fussed about B-road handling
Decent boot with room for bikes so looking at estate/hatch
Up to say £20K
Not too fussed about running costs as long as they're not crazy
I've had diesel manuals for years but happy to consider something else
I will run it for 3 years/60k miles
