140 mph in a '90 Jaguar XJ12 (Not mine) - Was floating a little. I pushed my old boss to "give it some" and he got ticketed at 100 mph on a back road in WI. We switched and he urged me to go. After 25 miles on the tollway at 140 he wanted the wheel back. No ticket for me (whew).
130 mph in my old '85 Merkur XR4ti. Floating badly. Stood on the brakes and they groaned loudly.
125 mph on '82 Suzuli GS750 and Yamaha XJ1200. The Suzuk wobbled so badly I was sure I would lose it. Too much tollerance in the swing arm bearings - even the new ones.

I have only had my '85 500SL Euro to 110. It's lowered with 16" wheels and 50 series tires. Solid like it's on rails. I'm still sorting it out and want to balance the wheels and such. I want to be careful while reckless driving. I don't get any track time so it's public roads that support this insanity. I love to go fast but fear speeding tickets.
