I was laughing at the comment about the Lexus.
Honestly, I thought you were laughing at my "And they don't own a pool" comment.
Lower middle class people don't drive Lexuses, new or used. The parts are too expensive.
Just an example. Lexus is considered the lower end of the "nice car" category. I've never owned one, so I can't speak about repair costs. I do know a guy who bought one (a used one) as his first "real car" (ie: not old beater), specifically because it was relatively inexpensive compared to other brand recognizable cars. Never asked him how much it cost to maintain. I do know the thing was absolutely thrashed when he finally got rid of it though.
