Used 2017 E43
I traded it in for a used E43 with 7,800 miles. I benefited from someone else's $30K loss in deprecation. It is a great car and the main reason for moving over was the AWD. I don't miss the E63 at all. The 43 is just as quick since there is never any tire spin or traction control intervention. It also get much better gas mileage than the E63. After having both, I like the E43 a lot and using common sense, I would recommend it. I only miss the snarl of the 63 and the big V8. To be honest, after 10 years of ownership, I needed the 500+ hp less than 1% of the time. It was a lot of fun though!
Getting back to your question, I think that owning both is silly. If you want a second car, get something different.
