5 series is a different beast in terms of premium feel, smoothness, poise and sportiness if configured right.

Just get a custom built M550i with adaptive suspension and other goodies if you are even asking the question. Money doesn't seem to be a huge issue, you are evaluating the value you get.

M340i is a track car to me, if you are going merino leather on M340i you are likely looking at the wrong car.

AND

You cannot get multi-contour seats in a 3 series, period!


Never would I spend ~60K on a 6-pot 3 series. Just got myself a 2020 540i was debating hard getting 340i instead for sportiness. Absolutely no regrets.
