I've done 131 in a 2 litre, diesel (yes diesel) 53 reg mondeo estate and it would've gone faster, but I was being very silly and came to my senses. I had no idea it could do that, but it just kept going, so I thought,
"what the hey, it's 3am on a pretty much empty m25".
When I was an even sillier boy, I went off the clock (130) in my 1990 Citroen AX GT, racing a BMW M3 and an Mondeo ST220 on the A12 between Colchester and Ipswich, the ST dropped out at 110, but the M3 guy kept pushing me. When we got to the Ipswich roundabout, I asked the fella in the BM and he said we were doing 138 on his clock.
Anyway, enough showing off. Cheers guys
