I think its a pretty tough call.
The OP isn't very clear if he is referring to Leasing vs. Buying a new car or a used car.
My first car I bought was a used car, I paid $8000 for the car, put in ~$4000-5000 in repairs, sold it a year and a half later for $5000. So basically I lost $7000+ in the short time I had it, besides for the aggravation I went thru, and the major hassle of not having a car for weeks (at the time when it was at the mechanic) ect.
If I would've leased I would have done much better.
I know this case is a little of a fluke, and not the typical, but I'm just trying to bring out a point.
Either way after all this, I didn't want to buy a used car so I bought a new car. I ran all the numbers, and it definitely was worth it for me to buy a new car over lease. (At the deal I was able to get, a 2011 Sonata for $18k)
Now in comparing between buying new vrs leasing... Over the first 3-4 years your payments will be higher when you buy, but once your car is paid off you won't have to be paying. When by leasing after 3 years, you have nothing and have to lease again. However over a 6-8 year period (based on that 12k miles is enough for you, and you don't smash up the car) then its not a huge money difference. You will save a few thousand dollars , but not enough to buy a bank
Also - even in my case, if I wouldn't have gotten a great deal on my car, and if I would have paid full retail - $22k, likely I would be better off leasing. (So buying new is only worth it if you get a good deal)
People like leases, as you have a new car every few years, and don't have to worry about repairs ect. It is a little of a luxury, but you are paying for that. I don't think that its called throwing your money out.
Regarding leasing a more expensive car, if someone has money what is wrong with him doing that. He doesn't have to live his life on a constricted budget. The higher end cars, drive better are more comfortable and this is a luxury the person wants to pay for. Would you call eating out and paying $200-300 monthly a waste of money? That how this person enjoys spending his money.
Just wanna add - that usually its easier to get approved for a lease over a car loan, so people with not such great credit might have no other option
