I think the Mercedes comparison (or the more common BMW) one is also useful for getting the idea that not every manufacturer is competing for the same segments but the prices in segments are generally close. No Mercedes is as cheap as a Camry but a Lexus is similar.

This comes up so often in these flame wars where people are really saying “I do/don’t think you need that feature” and won’t accept that other people aren’t starting from the same point. I remember in the 90s reading some dude on Fidonet arguing that Macs were overpriced because they had unnecessary frills like sound cards and color displays; I wasn’t a Mac user then but still knew this was not a persuasive argument.
