Cars are very similar nowadays as different manufacturers all edge slowly towards the optimum design. And I bet there's little quality difference, in the bought-in components at least, between a Bentley and a Ford.
I would take that bet on if I was a bookie, I work daily on all makes of cars from banger to well you name it and the chances are I have worked on one in my time, there is a huge difference. The very base material may have a bit in common but it soons stops.
