Yeah, I'll have that one as well, although for me it wasn't just taking it flat (that's easy in an MR2 with no power!) it was the first time I went up it on a sighting lap: Proper spine tingling stuff, when you're sat there recalling the duals in F1 etc over the years.
Maybe a bit big headed this next one, but another one was this year when me and the lads went to Donington for a trackday for my mate's 40th, and people threw me the keys to their cars to take them out as I knew the track better than they did. To a single man, they all came back in a little bit trembly and commenting that they had no idea how I could go that fast in a car I didn't know. Yes, massive ego boost, but I'd always considered them all to be much quicker and better drivers than me for the 12 years I've known them, and now to be considered as 'the fast one' amongst us was quite a nice feeling.
Still not a patch on some you guys on here though, like Brillo and Doc. One day though, one day...
