hit 160 on the autobahn recently myself, chickened out as the wife was with me and she made a comment about the tyre blowing out ... err that was it i'm afraid DOH!
the car had more to give, but the owners heart was not in it anymore

I hit an indicated 149mph on the autobahn before chickening out. In my defence the crosswind was strong, and the car stuffed with camping gear - my imagination got the better of me.
Car felt much happier at speed in our convoy to Gaydon last year ;-)
