I think Dennis will want at least a few more World Championships before he considers selling. He's not old, he's only 60. He's got enough experience to whip Alonso and Hamilton into shape if he wants to.
I agree. I think he would like to go out on a high not, maybe winning it this year or next if possible - back to back would be nice, but that's very imaginative thinking considering winning the championship this year is by no means certain. Ron is quite emotionally attached to the team and if he were to sell it I would like to think he would at least be given an honorary role or an advisory role.
