Based on looks alone, if those were the three actual cars, I'd take the M6. They are all similar in value and all sort of heavy and slow GTs but the 928 is downright ugly w those fender flares and wheels. It's strange that they are all in the same bland tone of beige metallic but the M6 actually looks good.
That generation of BMW was built extremely well. You can't compare it to some schit e36 you once owned or whatever it was. It would be an aging car now but same w the others. I never really wanted a 928 when they were new but they were nice on the showroom floor and on test drives with repair costs and reliability issues not yet on the horizon. They were super nice cars but kind of odd, sort of a German Corvette more than a Porsche to me. Very expensive when new as well so there was alway a new 930 for less $$.
The 8-series BMW just never registered w me.
