the early metro's appear to be 96.5 mm so will probably not fit.. later metros were 100mm will fit and allow you to role the car around the garage they would not be suitable for use on the road though.
there are plenty of other cars with 100mm pcd which would allow you to move the car around.
I'll concede you may be right Frank.........it's beginning to come back to me.......but I think maybe the wheel offset means no go...... There are no 'old' Metros left now... I understand the MGF is basically two Metro front subframes joined in the middle..
