What's your biggest irrational financial purchase/want?

Basically title. Just a fun post to see what other people have bought for their personal fulfillment, or really want to buy but know it's a dumb idea money wise.

I have this financially irrational want for a dirty diesel ute to do weekend warrior adventures in but have absolutely no use for it work-wise doing my indoor job as a health professional. I also bike to work, so it'd literally sit in the garage looking pretty most of the time anyway.

My wife thinks I'm stupid for wanting a ute, and my friends tell me I'd just be another wanker in a Ranger, but at this point I don't care as it truly has always been my dream car since I was a kid.

I'm in a position now to afford a nice one without needing to finance it, but know it's a dumb idea because that money could better be put towards the mortgage. I try to tell myself every time I see someone in a Raptor that I could afford one, but I'm making the smart decision by not buying one.

What cope do you tell yourself about your dream purchase/want? Or am I the only one!
