I think it depends on the item.
I've noticed with eating, that if the food is properly seasoned, I'm sated with very little. When it's lacking in salt, I tend to miss the internal cue that I've had enough, and want more of what I don't fully enjoy. This is what comes to mind when I think of luxury goods. Once I had a cashmere sweater, I never wanted any other. Not only could I pare down all other sweaters in my closet, I wouldn't shop again for any because the ONE I had is so perfect. When it's time to replace, I'll replace it.
Because it's 'luxury item' I have to take excellent care of it, I highly value it which furthers my enjoyment of it. Similar thing happened with my shoes and with sheets. I happened upon something so wonderful it obliterated everything else for me. The aesthetic value is for me alone, you can't tell by looking that there is anything special about my shoes or sweater. A low-end sweater might look just as good. My bedsheets don't impress anyone. There was a moment when having exactly the right thing eliminated desire for a host of other things. This reining in of wants is what makes me mustachian.
That the cashmere sweater was free and the high-end shoes are never worn thrift store finds is a bonus. The sheets I did splurge on, but for our custom size bed, it was somewhat necessary.
In the example of the Aston Martin, if buying it only fuels other expectations, it's a trap. But if the highly prized thing satisfies, leaving you no interest in all other luxuries, it's a different story.
