This is a good thread, OP, but this article is full of shit.
Why? Cars lose like a fifth of their value the moment you buy them. New cars are sucker bait. Go check KBB yourself.
MSRP for a basic F150 is $26,030 according to Ford's website. According to KBB's own estimator, a dealer will sell that same car with 10k miles on it for $23,676. So there's a $2.3k haircut for 10k miles on a car that can easily last 200k. 8% depreciation on less than 5% of the car's useful life!
And of course, that is what the dealer charges you, and of course you will get scammed. The real depreciation you incur is what you get from private sale. In this case, if you take amazing (top 3%) care of your F150, you can hope to get $22,403 for it. So you've lost 14% of the value of a car that's seen the low end of the typical usage for a year, and it literally looks like it just rolled off the display. More realistically, you can hope to get between $21,427-21,731 for this car that you bought a year ago and drove for only 27 miles a day: 17% haircut. I'll leave out the fact that a 2015 car probably retailed higher a year ago when you would have bought it and the 2016 model wasn't on the market yet.
Extrapolating from these figures, an F150 would be worthless after 6 years and 60k miles - this is of course nonsense, such a car is worth about $9-10k and dealers will ask 15k. The disconnect is basically the intangible "new car premium", aka idiot tax.
This is the other half of the retardation. Why care about such a useless metric? If I list my shitty truck on craigslist for a million dollars, does that somehow decrease your ability to buy a car?
Yes there are tons of cars 30k+ base price, and they easily go up to 100k if you throw in every overpriced accessory. These are luxury cars meant for people with money. Then there are also the truly absurd fuck-off-mobiles like Lambos etc, for people who don't ask the price when buying cars.
Realistically, if you care about "affordability", you would get a standard consumer car. It so happens that a year ago I was buying such a car, and compiled a detailed list of prices for new and used models. A decent small city car can be had for as little as $12k, and gets great mileage to boot. An SUV or light truck can be had for 20-30k. You can even get a hybrid for less than 20k, and get back 7.5k in tax credits.
Incidentally, the Jeep Wrangler in the pic, a luxury 4x4 that is stupid unless you plan to do a lot of off-roading (itself a hobby that is stupid for the non-wealthy), starts at 24k new - about what you could make in a year working minimum wage in many places (!!!).
