Never understood why anyone who still has to work 40+ hrs a week would buy a $150k car. Would you rather have something that gets $20k less valuable and costs you $10k a year in insurance... Or something that gets $10k a year more valuable and makes you $10k a year...
Sometimes a luxury good stems the psychic bleeding of feeling like you're looked down on and living a pathetic life. Also, not all people have access to a mechanism of growing capital (or the skill to deploy it successfully).
