<prompt> Human: So I use mint.com to track my finances and noticed today it hadnt updated the value of my car since I started with mint.com about a year ago. Turns out to update the value it uses Kelley Blue Book you have to update the number of miles on it.My miles in 1 year went from 80k to 85k and it depreciated...4,500!I didnt realize it would be such a dramatic depreciation. It is a 2011 Audi S4, stunning car, but my god man, to lose 4,500 dollars for only driving it 5k miles, almost a dollar a mile, not including gas or maintenance.Just thought Id put that out there. Next car is definitely NOT going to be a German luxury sports sedan. I make pretty good money and can afford it, and I have always loved cars, but dont think it is a very wise way of spending my money at all.  <response>: Cars are not investments. This is true of almost every good you buy. No one wants your old toaster, either.
