I know a guy who just had his brand new ~$38k truck totalled. He bought a $30k 2015 car. He's going to buy a 2016 truck when they come out. If the interwebs are correct, he's looking at around $8k in depreciation in the first year, and another $26k in depreciation if he owns the next vehicle for five years. That's $472/mo in
depreciation, not to mention the registration and insurance costs of a new vehicle vs something a few years old.
To compare, I bought a 2004 CTS-V for $12k in 2011 and sold it for $13k in 2013. My '99 Tacoma that I drove for 2.5 years also sold for more than I paid. Etc etc.
That's how I roll. I think it's worth $472/mo to take my route. If you feel that buying a new car is worth the additional costs, more power to you -- but I don't think most people actually realize how much they spend on shit. For cars in particular, a lot of people go with the mindset of "I can afford $xxx a month" and don't realize how much it actually costs in the end.
I do not feel that I am unhappy because of not buying more stuff. I spend the bulk of my vacation time traveling internationally. I don't have seventeen big screen TVs. I don't have ridiculous 24" chrome rims on my cars. I don't have a $120/mo cell phone plan. I don't have a $200/mo cable bill.
And I am happy.
IMO simply "buying stuff" doesn't make people happy. They just think it does.
