Great write up Transfer and I 100% agree with you even-though, I still have not picked up my M340 (at the dealer now).
In Feb of 2010 my E92 ZCP was the very 1st one to deliver to WA State. I completely custom built it and did ED which was an amazing experience on that car. Mine was equipped with a manual transmission which IMO was a mistake.
Once it got to the state side, driving a high revving V8 in Seattle streets was far from enjoyable and I started missing my E92 335. I ended up getting rid of the M3 before hitting the 5K mark after owning it nearly 3 years. I never felt like driving it.
When I test drove the M340 (I went into dealership with full intentions of ordering another 5 series), it immediately reminded me of my M3 but for something designed as to be a super fun daily driver......which is what i was shopping for. Order was placed shortly after and I am looking forward to spending next 3 years with it. My F10 was pretty loaded so, I did order most of the gizmos but non of the self driving stuff and I left the adaptive suspension out. I have also kept the 18" wheels with non-RFTs which I am looking forward to.
Having said all of that, I do miss looking at a beautiful ZCP as a garage queen
