approx. 125 mph in the cobra... no fun above 100
approx. 150 mph heading North on the German autobahn in a BMW 535 ("road train / convoy" of 4 cars in the night... I was last in line letting the front clear the left lane for a little hour on our way home from skiing
But the most fun on... a brand new Volvo R was giving me the angry lights from about 5 Feet distance - wanting to pass me badly... I was in my "sleeper" 1998 Saab 900 convertible on the highway doing 85 mph - when Right lane was free I changed lane, but the very moment he came passing at full trottle I let the turbo rotate... at 155 mph he gave up
( cars in Europe are often restricted to mph 155 and my mechanic have had my Saab at 175 mph
)
