A Lexus is a re-branded Toyota; it's still high-end.
I would have gone with something like Ford and Lincoln, where they really are almost completely rebadged.
You mention "interiors are upgraded, accessories are upgraded" - a 2010 Escape looks and feels cheap. Plastic everywhere, everything creaks and squeaks when you lean on it a little. The Lincoln has (actual) wood paneling, things like retractable running boards and even a nearly ten year old Navigator feels nicer, so I'm not sure how you can say it's not like the Toyota-Lexus difference.
