That's not a very well thought out thing to say.
I drive a 2002 that has a good running engine but is otherwise in decline and the value of the car makes the fixes to get stuff working not worth it. The cd-player doesn't work, the heat doesn't work, has terrible sound isolation so it picks up lots of road noise, the dashboard rattles when you get going fast enough, and the seat/steering wheel only have a handful of adjustments. I used to commute 1+ hour each way to work, had a rental just before I moved. It was a newer car, not a luxury car, just new and it made a tremendous difference to the commute. Less road noise alone was awesome.
I don't know if a new luxury car would be a lot more of an improvement over a new commuter sedan but a new car absolutely makes a difference in a long commute.
As for the car making the person not a single person has mentioned buying a new luxury car solely for how others will perceive them. The vast majority of people buying nicer cars do so because they like driving them or like the options not because they care what others think.
Luxury cars, unlike say expensive AV cables, actually do offer more for the money. It may only be incrementally more but it is more.
