Leased mine. Treated it as a long term renting/ test drive to see if I really like living with it.

Also because...
1. I fit into the category of people that tends to like new cars in a few years (No matter how much I think I'll commit to owning it more than 3 years..)

2. When inquiring about the vehicle the residual and MF (interest rate) made the monthly extremely attractive. (For the 3 year "test drive")

3. The "accidents." Car's value not only dip the most because of depreciation over time. But also when the unfortunate happened.
For example, your 2 year old M5 got an accident on the report, which could dramatically curb your trade-in price (Compare to if your M5 is say, 5 years old)
Not to mention the bad feeling of owning a previously damaged car, and the fact that you'll lose more if you want to get out of it...
With lease, just return it at the lease end. If all is repaired properly through insurance, you shouldn't have to bare any additional liabilities.

And you can always find another similar year/ CPOed/ better condition examples if this year/ model of M5 really speaks to you.
Hence why my e36/ e39 are here to stay. and the F80/ F87 were ones I've sampled and decided to part with at lease end.

So yea, I'm the leasing camp
