Actually it's depend on the usage priority
> Looks
> Fuel Consumption
> Maintenance for next 10 years (forecast longer, better than sorry)
> Cabin comfort, as you spend over hundred of hours inside over the periods
> Usage, try to propose highway / city drive, the easiest way is take the total travelled mileage, then split into both / total mileage per fuel, average will do
> Capacity, I believe it's not that huge differences between 2

Both cars are not hard to maintain as S70 parts and workshops will be available over the time like X70 case.

Brand experience, me personally not favor ETCM as a ex Grand Livina owner, but its indeed a good car. No complaint on the build except lower arm lembek thus easy to break.

It's better to have a test drive on both in the same day so that you can compare on the spot. Myself even test drive more than 1 unit for the same model to ensure the driving experience is match with each others.

The advantages of establishment over few decades vs a relatively new (less than 10yo Proton "China")

Like I said, parts and aftermarkets stuffs will be available over the time, it is not an overnight story, to me it's good enough that the manufacturer vowed to solve parts issue, regardless what happens to the original country, it's depend on consumer want to bite it or not.

Hope that the TS can made up his mind and get a suitable ride for himself
