$37k in 2016 money is about $61k today. Crazy, but it is what it is. You can get a new 340i that is better in every performance metric than the SS. That is the sport sedan standard.
m340i is a hell of a car. However, it is not better in every performance metric than the SS - per Car and Driver testing. It is decimals faster in the quarter mile but a couple decimals worse in the skidpad g's. Braking from 70-0 mph took 159 feet in the SS vs 157 in the m340i. Acceleration, handling, braking - the performance metrics - are basically a wash. For the subjective sports sedan topics, both can be had in RWD but only the SS had a manual transmission. Some say RWD is a "sports sedan", others say AWD - which could not be had in the SS - is more sporty to them. Some say it CAN'T be a sports sedan without a manual transmission, obviously others disagree with that. Manual transmission hurts acceleration in modern cars, but can minimally improve handling due to less weight. As far as price, the base m340i in 2026 is right at the inflationary number you shared at $62K. But you can option those up to $75K to get the best performance which is what Car and Driver had on the m340i they tested and was a wash with the $61K equivalent SS.
