Point taken, and I agree, in order to maintain the warranty and get fair value at the end of the lease you have to do the scheduled service. That's not what I meant to say. I'm talking about a lessee who leaves the sunroof/window cracked when it's raining, or uses cheap/low octane fuel, constant hard driving... Lease, imo, often equates to a utilitarian disposable commodity much like a rental where as long as you don't ding it you don't have any responsiblity or motivation for babying the car. I'd rather buy a car from the original owner with documentation than pick up one that's just been turned in at the end of a lease no matter how well it's been serviced.
As someone who leases luxury cars himself, as someone who'se father leased luxury cars for 30 years, and as someone who knows a LOT of people who lease luxury cars (almost everyone in my profession leases) I disagree. Most people, even when they lease, see it as a significant use of financial resources and treat the vehicle accordingly. I mean, leasing an LS costs around $1k a month, thats not a insignificant amount of money to anyone.
I agree with you that on the whole owners are going to take care of the car better than lessees. However, if you're looking at a 2-3 year old car theres not going to be a significant difference in the quality of the car whether it was owned or leased. If it was owned and then traded in 2-3 years it shows that the owner didn't have a long term plan with the car and that they aren't concerned with significant financial loss. How is this different then how you're categorizing people who lease cars?
I would have absolutely no fear buying a pre-owned car of this caliber that had come off a 2-3 year lease. Who cares if they never vaccumed it, washed it, or conditioned the leather. Those are things you can see when you examine the car, and since the car is so new those are things you can remedy and it won't have any lasting effect on the quality of the car. As for hard driving, you can see evedince of that in terms of curb rashing, suspension wear, rattling and looseness, etc.
