It seems like finding a hard top M30 or any M30 is hard to come by. My father owned a 90-91 (not sure the year) M30, hard top black with gray interior. It was the first car I drove when I got my license. I loved that car. I have been trying to find with the exact color, but to no avail. In the event that I do find one, is there anything I should look out before purchasing? Corrosion issues? Common mechanical issues?
