the headbolt issue affected all 63's through mid 2011.

so you want the MY to be 2011 onwards to be safe. you can look up engine number as well. but to be extra safe just get any 2012 63 onwards for the updated bolts. If was not a matter of if with these had bolts, but a matter of when they were going to fail.

have owned a 63 myself (non headbolt issue one)
