We recently purchased a 2 year old vehicle for my wife, and I was surprised at what a reasonable bargain they were compared to new. There's really no reason to dump a perfectly good vehicle after just 3 years, even a 6 year old vehicle. It has a lot of miles left in it and you might as well take advantage of it.
Leasing (in my opinion) is financially stupid, and best left to those who don't know any better or feel the need to live beyond their means. Once the lease is up you've made payments for 3 or more years with nothing to show for it. It's good for automakers and dealerships, which is why they push leases so hard.
I don't think you really understand leasing. While your blanket statement used to be true, it's no longer true now and it depends on the deal the automaker is offering. Check out leasehackr.com for the latest lease deals. On some leases, the monthly payment is so low, that it's worth it over buying. Part of the reason is due to manufacturer incentives that you can apply to the lease payment. If they're offering a 5k rebate, you apply that to the monthly payment which can be 2-3 years. A 5k rebate on a purchase is a lower percentage discount. You just have to do the math on each deal instead of just saying that they're all bad. And if you're buying a luxury car and tying up 40-50k in the car, it may make sense to lease for $400-$500 a month instead, especially if the market returns an average of 8% a year although the market has been pretty weak the last couple of years.
But the math for leasing vs buying a used car is different. You can usually get an extended warranty with a used car which will cover at least 3 years. A used 3 year old luxury car is probably in the 20-30k range and will probably still be worth at least 10-15k in another 3 years if not more. So that's 10-15k depreciation over 3 years instead of 20k+ on a new one so it's still cheaper to buy used instead of buying/leasing new.
