The torque dip isn't really a massive issue. Keep the revs up and it is fine. A lot of us have sorted this with a manifold and remap. Makes a big difference to mid-range torque.
The car never had a reversing camera. You can fit an aftermarket unit to do this to the stock head unit.
Plugs are only changed every 60K. Yes a pain to do and a more expensive service, but you don't have to change them often.
Auto gearbox is reliable. It only really has limitations if you go turbo, but this can be managed.
As for important parts of the service history, spark plugs at 60K, fuel filter at 80K and also that the diff oil has been changed every 20K. Some dealers seem to skip this.
2012-2013 cars that the valve spring recall has been done, also steering harness recall in 2016.
There are no real issues with rust yet.
