Here are the numbers I'm using if it helps. Don't get me wrong, I think the typical advice to buy a reliable, used car (if you need a car at all) is excellent. I was just surprised when I discovered these non-car-dealer companies that lease new vehicles, and when I did the comparison, it was not nearly as much of a difference as I would have thought.
Here's what I leased, and some of the other total costs. I'm going to leave out any factors that I think would be the same regardless of leasing vs. buying, since I'm assuming you'd get a similar car either way (i.e., not comparing a Civic to an SUV). For example, mileage would be about the same, so it can be ignored:
Leased 2012 Honda Accord (family of 5, so I wanted a decent-sized sedan)
------------------------------------------------------------------------------------
-Monthly Lease: $190 ( 3 years, 12,000 miles/year allowed)
-Upfront costs, any amount due upon return of the vehicle, etc.: $0
-Expected Annual Maintenance: $150 (about $12/month) - everything is under warranty
-Collision/Comprehensive Coverage: $35/month
Total cost of "ownership" amortized monthly: Approx. $240/month
Buying a decent used, mid-sized sedan
--------------------------------------------------
- Cost of vehicle: $7,200 - If I assume this car would last 10 years as an average and then be pretty much worthless, that would be $720/year or $60/month
- Expected annual maintenance -- highly variable, I estimated an average of $130/month (you could go years with just oil changes and minor repairs, but then have to replace the transmission and tires at a very large cost)
- Collision/comprehensive coverage: $0 -- Now I don't know how to factor this in, because if your car is totaled and you can't collect from an insured, at-fault driver, then you're screwed for your entire replacement cost. So maybe an unfair advantage here, but let's leave it at $0 to be generous
Total cost of ownership amortized monthly: $190/month
Additional Cost to Lease = $50/month ***
*** I completely understand there are assumptions baked in here, which I think are a necessary part of the equation. There are unknowns such as how long the used car will really last, how much repairs will really be, how much of your value you would lose if the car was damaged, and so on. And that's kind of my point -- in this case, having a completely warranty-covered, insured, super-safe with full curtain airbags etc., won't likely break down in the middle of nowhere, kick-ass new vehicle is worth $50/month to me. I'm all for buying used, but it does come with some uncertainty not knowing how well it's been cared for, when parts will give up the ghost, and so on.
Once this lease expires I might buy used for my next car. I was just surprised you could actually lease a brand new car at a pretty low cost comparatively speaking
