Possible new purchase - Outback 15-18, things to look for?

[stevet180]

Hi all, looking at buying an outback, have been looking at cars aged 2015-18 with 50-100k on. Is there anything I should be looking for when viewing these cars, any particular areas that are prone to rust etc? Anything that should have been done as part of the service routine?
I won't go near a VAG DSG engine of this age because of issues with the DSG boxes, can I presume the Subaru CVT system is more robust and will last a lot longer with proper servicing?
Thanks.
