The only person that believes your 8 year old car is better than a new 328i is you.
At any rate, I’m not a realtor and thus not part of the 1%, so my idea of fun more or less applies to the 99%ers.
A 328i is realistic for many, a M3/5 and a lot of other car you mention is not.
A BMW M Series borders on the exotic.
BTW AN, I tore up a G37 today in the carpool lanes. Once the powerband kicks in on my 328i the only thing you’ll be seeing is my dorsal fin (that little fin thingy on my roof).
