120mph recently in my '87 190E 2-litre 5-spd with 125K miles, about the same in an '84 BMW 320i.

100mph approx (speedo only reads to 95!) in my '70 Morris Traveller with 1275cc MG Midget engine.

80mph in a 594cc Fiat 126, going downhill (my first car)

I always feel the need to max my cars to see what they'll do.
