THIS.
I just went through this a about a year or so ago. Was looking to replace my small pickup. Had low $20K saved up but couldn’t find any decent used trucks with low mileage so started looking at new trucks. I got pretty fired up and caught up in looking at new trucks and pretty soon I was testing driving and considering truck pushing into the $30Ks (I was looking to buy small pickup, not full-sized…even though I started driving a few of those too). Would have been a piece of cake for me to “afford†the more expensive truck than I planned by paying cash and just financing the difference. Emotionally, I was close to being there.
In the end, I held to not financing and writing that painful check (yes….it is painful…which is part of the point). I still got a new pickup (manual trans, manual windows/locks) but spent far less than what I would have had I financed. Yes, I probably could have gotten 0% loan and paid off within the required terms, but it wouldn’t change the fact I would be $10 - $15K poorer I am today.
