Mayday - Vehicle age restriction?

Hello I currently se Green Flag but wont be travelling overseas this year so I was thinking of using the club's Mayday as a cost cutting excercise. 

Is there an age retriction for using the service?

Currently Green Flag charges me £10 more a month because my vehicle is over ten years old. Is this the case with Mayday also?

I can't find anything on the policy T&C's so I thought I would ask here.

Many thanks... John
