In my personal opinion, as having had a total of 8 turbo cars ( toyota starlet turbo jdm, subaru impreza sti 98 jdm, evo 6 tommy makinen , evo 7, evo 8 and a E92 335i) i can tell you that Turbo engines when they get really warm, you can def see a consistent decrease in performance...while nat aspirated engines will keep punching like cold...
Keep the M3, its a classic.
Agree with the above. Heat soak is a bitch.
