Around 160-something as a passenger in the old C&B RS Turbo a long while back. Probably in the 150s in a couple of Cossies.
Never been that quick in any of my Fords, as I'm not that fussed by top speed really. Think I took my old 850 T-5 up into the 120s on the clocks, racing an E46 M3
Happy to sit at 70 really though. Acceleration and hooning about down country lanes is far more fun than top speed, and you can have plenty of fun without breaking the limit
