I had a Porsche Carrera race tuned 911 for two weeks while the boss was away ,and it was scarily fast , Also a VW corrada vr6 twas a bit nippy on the M6
I've had a few fireblades, ride them to work. they do just above 55mph but only if I get really low and aerodynamic shaped.
Ferrari Testarossa but didn’t open it up fully, fastest I’ve been is 150 on a Honda Vfr Fastest in a car 140 in a Mitsubishi Lancer Turbo , the original Evo.
Tricked up ZZR. Saw 180 before my eyesight turned to a complete blur! Likely somewhat less than that in real terms but the world goes past you very quickly at those speeds.
Drove my mate's race-prepared Caterham round Donnington. Scared the Marmite out of me. Then he drove me round (he's a former Roadsport champion) and I was approximately five times as scared as we all-wheel drifted round impossible corners never going less that 75mph even on the tight ones and getting the tyres over every kerb to the max.
Honda C90. Ok not the fastest vehicle but it was on a Greek island and I was riding it wearing trunks, flip flops and a vest...(or singlet if you prefer) so at 30 mph it felt scarily fast.
I was given a track day present for my 40th, so I got to drive an Audi R8 and a Aston V12. But, I think I got the fastest speed out of the Aerial Atom - not sure what speed. I used to work for an exhibition company, and a few weeks after starting we were building a show at Silverstone for Top gear Live - much better on a track than in an exhibition centre (and no sign of the dickhead Clarkson). I got to take a Skoda pick up, an Octavia and a Lotus Elise - easiy got over 130mph :-D On the road I remember slowing down from 125 in my Nova SR (heavily modified) and got done for doing 97 by the rozzers!!!
Mrs Geord treated me to a driving experience so I drove a Ferrari for three laps it only lasted about 5 mins One of my favourite cars are BMW E30 325i sports just love the looks, nightmare in the wet.
