Way too optimistic buddy. Ford never wanted my Focus or your Escort to last as long as they have. Cars that last lead to less new car sales. As reliable as cars are expected to be today, they OEMs are also trying to keeps sales up. I'm not going to start on about conspiracy theories and tinfoil hats we should be wearing but the ideal customer is someone that buys a new car, doesn't put much money into it assuming it is an indication of reliability, experiences catastrophic failure, thinks to the self "it was a good car until it died, I should get another" and returns to the dealer to buy another shiny new one. OEMs hate people like us who keep their cars going long after their life expectancy is up.

That oil bathed belt sounds like a recipe for disaster on top of the idea that turbos wear and develop excessive shaft play and intercoolers clog with oil from blow-by leads me to think that those cars/engines aren't going to last much past 125,000 miles unless religiously maintained. Junk yard puluts will probably not come with intercoolers and the turbos will need to be replaced or rebuilt, if that is possible.
