I had a so-so experience with a lease return at Infiniti, let alone a used one with unknown accident issues. The lessor had clearly not maintained some things, although the basics were done.
So, my 1995 Q45, purchased in 1998 with 50k miles (which was low enough that I thought things would be okay) had a transmission failure at 104k miles - soon after the extended waranty I bought ran out!

That is when I decided doing the basics of oil changes, etc., was not enough for these expensive cars.
I also decided to buy new from that point on (as I had done in the past) so that I would know the history of repairs, maintenance, etc. Of course, this is not possible for everyone, but I can afford to do so, because of the way I buy cars. I pay cash outright (because I pay myself the money monthly for the
next car!) and keep them a long time, and don't waste frivolous money on things like expensive wheels, etc.
Based on how I save for cars ahead of time, about 8 years after I graduated from college, from my third car on, I have not had a car payment!

This does not work for people who think that they need to buy the best cars possible right out of college and add debt on top of a depreciating value ... essentially for the rest of their life.
