Between 135 and 140 in a 1992 MB C280 down an old country road (This was probably back in '95-'96). I don't remember the exact speed at the moment, but it was definitely over 135.

Most recent was 118 in a '98 SL500 a few months ago (old country road again).

Both times were pretty scary, but worthwhile. Also, the cars didn't seem to be anywhere near their peak... It was just time to slow down.

Once you become concerned that glancing at the speedometer to see how fast you're going will affect your driving, it's time to slow down.
